For product design in the pet supplies industry, it is essential for development teams, procurement personnel, and brand managers to have a comprehensive understanding of the various types of pet carrier bags. This knowledge forms the foundation for planning new product lines or evaluating supplier capabilities. In this guide, we will explain the history of pet carrier bags, commonly used styles, and their specific functionalities, helping you build a clear product roadmap.   1.The development process of pet bags can be divided into four stages：   1.1  Early Stage (Early 20th Century): Practical Transportation Containers Single Function: Primarily used for transporting working dogs (such as hunting dogs and shepherd dogs) or carrying racing dogs. The materials were rough (such as canvas and metal cages), focusing on durability rather than comfort. Simple Design: Mostly open baskets or simple backpacks, lacking ventilation and safety features, resulting in lower comfort for the pets. Usage Scenario: Mainly used for functional transportation rather than daily companionship.   1.2  Functional Stage (Mid to Late 20th Century): The Material Revolution Transformation of Pets' Role: Pets gradually became family companions, and the demand for "carrying pets while traveling" increased, driving the commercialization of pet carriers. With the material revolution, the use of lighter and more comfortable materials became possible. Material Optimization: The use of lightweight materials such as nylon and Oxford cloth reduced the weight burden. Ventilation Design: Mesh windows were added to improve air circulation. Safety Basics: The inclusion of leash attachments, internal buckles, and other safety features. Emergence of New Types: The differentiation of types began, including backpacks (to free up the owner's hands) and airline-style carrier backpacks (with hard-shell structures, suitable for cats or small dogs).   1.3  Professional and Specialized Stage (2000-2010) Scene Segmentation: Air Travel: Soft-shell or hard-shell backpacks that meet airline standards (e.g., foldable expandable types). Outdoor Hiking: Lightweight, durable materials with additional features such as water bottle pockets and storage space. Urban Commuting: Fashionable appearance with concealed designs (e.g., "space capsule" transparent window backpacks). Improvement in Pet Comfort: Structural Optimization: Ergonomically designed straps and adjustable chest straps to distribute weight. Functional Details: Shockproof bottom panels, removable soft padding, urine pad layers, and water dispensers. Safety Upgrades: Reflective strips, breathable ventilation holes to prevent suffocation, and reinforced locks   1.4  Smart and Humanized Stage (2010-Present) Integration of Technology and User Experience as the New Focus Smart Features Integration: Ventilation System: Built-in small fans or ventilation holes to optimize airflow. Temperature Control Design: Heat-insulating materials or layers that can insert ice pads. Smart Accessories: GPS tracking, lighting, cameras (which allow owners to check their pet's status via a mobile app). Enhanced User Experience: Lightweight Materials: Carbon fiber frames and aviation-grade aluminum to reduce the burden. Multifunctional Expansion: Can be folded into a pet bed, or connected to car seat belts. Personalized Design: Custom colors, collaborations with trendy brands (e.g., fashionable pet backpacks). Health and Environmental Considerations: Antibacterial Fabrics: To prevent bacteria growth. Eco-friendly Materials: Polyester made from recycled plastic bottles, biodegradable components. The evolution of pet backpacks is essentially a reflection of the deepening relationship between humans and pets — from tools to companions, from function to emotion. In the future, innovation will continue to revolve around the "symbiotic experience." Below, we will elaborate on this topic from two dimensions: design features and functional segmentation.   2. The Design Structure and Functional Segmentation of Pet Bags   2.1  Classified according to external morphology 2.1.1  Double-Shoulder Backpack Style (Pet Backpack) Structural Features: This is the most common and mainstream style, resembling a regular backpack. It is carried with double shoulder straps, which helps distribute weight evenly and frees the hands. It usually has a hard or semi-hard shell and includes an internal safety leash. Structural Advantages: Comfortable, labor-saving, and allows flexible movement. It is suitable for carrying and moving over longer periods. Subcategories   1）Cat Backpacks  Cat bubble backpack ： This is the most popular style, featuring a spherical transparent “bubble” window on the front, typically made of PC or acrylic material. The sides usually use reinforced breathable mesh, EVA back panels, or supporting plates to form a semi-hard or hard shell structure that prevents deformation and maintains a stable interior space for the cat. During production, it often requires reinforced bottom panels, scratch-resistant and wear-resistant materials, and safety-ensured ventilation for the front or side windows. Smooth zipper operation is also crucial to prevent cat fur from getting caught while opening or closing. Cat carrier backpack ：The appearance is similar to a regular backpack, made with relatively soft materials. Three sides feature tear-resistant PVC mesh to ensure ventilation and visibility. The backpack is foldable for easy carrying and is suitable for lightweight small to medium cats and dogs for travel and outdoor walks. Cat hiking backpack：This cat hiking backpack emphasizes carrying comfort and helps distribute shoulder pressure, featuring padded shoulder straps and back support. Its materials and design prioritize durability, comfort, breathability, and safety. The outer layer is made of waterproof, tear-resistant nylon, with a breathable mesh lining inside. The bottom is reinforced with EVA panels, PP boards, or thickened Oxford cloth, while mesh windows on the sides and top provide visibility and ventilation. An expandable design increases interior space, reducing discomfort during long trips.   2）Backpack for dogs / Dog Rucksack Dog travel backpack ：Dog backpacks generally feature a top full-opening or large-opening design, allowing active dogs to enter and exit easily. Designing an excellent dog travel backpack should follow the core principles of “pet comfort first, owner carrying ease, and versatile scenario adaptability.” The main fabric should be high-density nylon with tear strength ≥800 N and a waterproof coating. A breathable mesh lining quickly wicks away moisture. Mid- to high-end models may include integrated sensors, with an app displaying real-time data inside the backpack and automatic alerts if thresholds are exceeded. A reinforced bottom board combined with a spine support ensures that the backpack does not deform or collapse even when carrying up to 10 kg Puppy Backpack Carrier ：Puppy backpacks require a softer internal space and a more stable bag structure. The body of the backpack is typically made of denser breathable mesh, such as sandwich mesh, and the interior is equipped with a thickened padding for added comfort. Additionally, the top features an adjustable, escape-proof design for enhanced security.   Main Differences in Design Between Cat Backpacks and Dog Backpacks Design dimension Dog  Backpack Cat  Backpack Structure and Opening Size .Focus on interaction and easy entry: Often features a full top opening or large opening for active dogs to quickly enter and exit. . Encourages standing and observing: Many designs allow dogs to place their front legs on the edge of the backpack with their head fully exposed (e.g., chest packs, basket-style). .More open structure. .Focus on safety and closure: Typically has a closed design with doors on the sides or top to prevent escape. .Forced concealment: Smaller entrance, usually dark or semi-dark interior, in line with cats' instinct to hide. .More enclosed structure (e.g., airline-style, most soft-shell packs). Interior Space & Posture .Allows multiple postures: Designed so dogs can naturally sit, lie down, or stand inside the backpack. . Focuses more on joint comfort for dogs. .Prioritizes curled posture: Space is designed with a curled or lying posture for cats, typically discouraging standing. .Emphasizes the sense of security created by the feeling of being wrapped or confined. Ventilation & Visibility .Visibility prioritized: Large mesh windows, even transparent windows, allow dogs to observe the outside world, reducing boredom and anxiety. .High ventilation requirement, often combined with visibility. .Balancing safety and ventilation: Visual observation windows with a cover allow cats to have control over their environment while maintaining airflow. Safety Design Focus .High weight-bearing and balance requirements: Dogs are usually heavier, so the straps, chest straps, and waist belts need to be highly professional, especially for medium to large dog backpacks. . Emphasizes long-term carrying comfort. .Lightweight and stability: Cats are lighter, focusing on the backpack's lightness and fit to reduce wobbling (cats dislike instability). Ergonomic design primarily for the owner's comfort, not for extreme weight limits. Special Features Tendencies .Work and expandability: Features like attachment points, water bladder compartments, and “saddlebag” designs that allow dogs to carry their own items. .Outdoor-focused: Emphasizes durability, water resistance, and handling complex terrains. .Stress management: Features like expandable resting space, privacy curtains, and enhanced shock-absorbing designs. .Airline compliance: Hard-shell cat backpacks often directly match airline cabin size regulations. Materials & Cleaning .Outer layer: Emphasizes high abrasion resistance, water resistance, and easy wiping (since dogs may drool or get dirty). .Interior padding: Removable for cleaning, but focuses more on durability. .Outer layer: Focuses on lightweight design and scratch resistance. .Interior padding: Must be fully removable and easy to clean since cats may vomit, urinate, or shed (hair) due to stress.   2.1.2  Sling bag Subcategories 1）Cat sling / Cat carrier sling : Cats lack a sense of security and prefer to curl up more naturally inside the bag. Therefore, cat sling bags are usually designed to allow cats to maintain a sitting or lying posture with strong wrapping. Some cats may like to stretch their heads out of the bag to observe the world, so the design will take into account the size of the opening and safety. Typically, a zipper closure is used to ensure that the cat cannot easily escape. The fabric is selected to be soft and skin-friendly, with a focus on the width of the shoulder straps, support structure, and internal safety leash. 2）Dog Sling Bag / Dog Carrying Sling / Puppy carrier bag ：Compared to cats, dogs are usually more active and enjoy looking around or interacting with their owners. Therefore, dog slings are often designed with larger openings to satisfy their curiosity about the environment. They typically include a dedicated safety leash to prevent the dog from jumping or escaping. Since dogs are generally larger, the design emphasizes close support and shoulder load reduction. The materials are usually soft fabrics, such as cotton-linen blends, twill, and reinforced mesh. Key design aspects include shoulder strap width, support structure, and internal safety leash.   2.1.3 Pet Tote Carrier / Pet Purse Carrier / Soft Pet Carrier Bag/ Dog Handbag Subcategories 1）Dog Carrier Tote ：These dog tote bags are often designed to combine aesthetics with practicality. The materials commonly used include ultra-light nylon twill and taffeta fabric with padded stitching. The handles are usually finished with PU leather trim, and the bottom of the bag features a removable padded insert. When not carrying a dog, the insert can be removed, instantly transforming the bag into a fashion purse carrier. 2) Dog Handbag ：Dog handbags place greater emphasis on the style and feel of the materials. They often use fabrics such as embossed PU or velvet-like PU leather, maintaining basic space for the pet while ensuring the owner's fashion taste remains on point. Overall, higher standards are applied to leather quality, stitching, edge finishing (such as edge painting), hardware texture, and corrosion- and rust-resistance of the metal components.   3）Dog purse / Dog purse carrier / Puppy purse carrier /Cat Purse Carrier：A purse carrier is a pet carrier bag designed to resemble a fashionable handbag. It is usually smaller than a tote bag, making it suitable for carrying small pets such as puppies and cats. Common materials include leather, fabric, and nylon. Its stylish appearance allows it to be used as a daily accessory, especially for taking pets to shopping, restaurants, cafés, and other social venues. 4)Soft Pet Carrier Bag：A soft pet carrier bag is a pet bag made from soft materials such as canvas, nylon, or polyester. It is typically used for carrying small pets, such as cats or small dogs, during daily outings, short trips, or visits to the veterinarian. Key design and craftsmanship considerations include the proportion of breathable structures, scratch-resistant lining materials, reinforced shoulder straps for load-bearing, and the use of eco-friendly materials that meet export standards.   2.1.4  Cat Carrying Case/Padded Dog Travel Case / Pet Travel Case 1):  Cat Carrying Case：These are mostly hard-shell cases, requiring injection molding or thermoforming processes. Strict standards apply to the locks, ventilation openings, and the case’s compression resistance. They are sturdy and provide excellent protection for pets (against crushing), with relatively independent interior space, making them suitable for placement on car back seats or for short-distance carrying. 2）Padded Dog Travel Case / Pet Travel Case：Travel-style bags usually feature multiple compartments and a large-capacity design, requiring extensive stitching, edge binding, and anti-deformation craftsmanship. The fabrics are primarily durable nylon or blended Oxford cloth, with reinforced frames added to maintain the bag’s shape.   2.1.5  Pet Carrier on Wheels / Wheels Pet Carrier Bag：Pet rolling bags typically use a lightweight aluminum alloy telescopic handle and a PP/PC board base. Production focuses on the durability of the wheels and a structural design that evenly distributes stress across the bottom.   2.2  Classification by Specific Function 2.2.1  Cycling Pet Carrier Bag 1）dog backpack for biking：Backpacks designed for cycling with dogs should be lightweight, wind-resistant, and feature a stable, close-fitting structure. The shoulder straps must be widened and equipped with a chest buckle to ensure the bag remains secure and does not sway during rides. 2）Dog Backpack for Motorcycle / Motorcycling Dog Backpack ：Cycling dog backpacks must offer high stability and shock resistance. The fabric is usually made of windproof and waterproof nylon, with internal cushioning structures. The shoulder strap system must feature thickened, anti-slip padding. 2.2.2  Backpack for Dogs / Dog Backpack 1）Dog Hiking Backpack ：Outdoor hiking backpacks primarily use durable fabric combined with large breathable mesh structures. Production focuses on frame stability and proper distribution of shoulder load, often incorporating chest or waist buckles for secure fastening. 2）Daily Dog Backpack ：This is a wearable pet backpack, with a focus on the stability of the shoulder and chest strap system. During production, special attention must be paid to edge binding with rubber strips, reinforced stitching points, and the tensile strength of buckles to prevent shifting or slipping when the dog runs. The design also needs to allow for adjustable space to accommodate different dog body types. 2.2.3  Pet Treat Holder / Dog Treat Holder : Small treat bags have a simple structure but require convenient opening and closing as well as oil-resistant interiors. They often use inner layers with waterproof coatings or TPU linings. 2.2.4  dog poop holder / dog poop bag carrier : These are small functional accessories, emphasizing lightweight, waterproof, and durable design.  Production focuses on smooth zippers, proper opening for roll-bag outlets, and the sturdiness of hooks and webbing. They are used to carry dog waste bags.  Inside the carrier, there is usually a rotating spindle to make it easier to pull out plastic bags smoothly. The exterior of the carrier often features a metal clip, allowing it to be attached to items such as a leash collar, backpack, or leash.   3.Summary   Pet bags cover a wide range of designs, from daily commuter bags to outdoor hiking backpacks, and from tote bags to rolling travel cases.

8-Step Breakdown of the EVA Thermoforming Storage Box   The complete manufacturing process of a thermoformed EVA case can be divided into eight stages: EVA material preparation →Selection of Surface Materials→ EVA cutting → logo or pattern processing on boxes → pre-pressing → thermoforming → cooling and trimming→ stitching, then inspection and packaging, a versatile EVA storage box is completed. The key process parameters are concentrated at the thermoforming stage. Below is an explanation of each step in order, along with commonly used control ranges, making it easier for brands to reference directly when designing and customizing pencil cases or EVA storage boxes.   1. EVA Material Preparation   Select EVA with suitable hardness: depending on the required wall thickness and firmness of the pencil box, choose EVA foam sheets with a density of 200–300 kg/m³ and a hardness of 55–80 degrees. For lightweight small EVA cases - such as eyeglass cases or ipod case -EVA with a hardness of 65 degrees is recommended. For tool cases or electronic product storage box, a hardness of 75 degrees or above is recommended to ensure the case maintains its shape and does not deform easily.   2. Selection of Surface Materials for the Case   After choosing EVA sheets with the appropriate hardness, the next step is selecting the surface fabric to be laminated onto the EVA sheet. The most commonly used option is polyester knitted fabric, which has a smooth surface, excellent elasticity, and relatively low cost - making it the first choice for most standard EVA cases. In addition, customers may select customized materials based on their product requirements or brand positioning. For example, PU leather laminated with EVA is often used to make item such as pencil box and EVA organizer case.   3. EVA Laminated Sheet Cutting   Lay the laminated EVA sheet flat and cut it into individual pieces. The cutting size should be approximately 20 mm larger than the perimeter of the mold. This extra allowance ensures that materials with different shrinkage rates have enough room to stretch, and it also prevents material shortage during the thermoforming process.   4. Laminated Fabric Surface Logo or Pattern Decoration   4.1. The decorative patterns or logos on the EVA box can be silk screen printing or heat-transfer printing or sublimation print. These prints will not be affected by the subsequent thermoforming process.   4.2. Debossed logo: The pattern or logo can also be debossed directly onto the thermoforming mold, allowing it to be formed in one step. In this case, no additional logo decoration is required as above.   5. Pre-pressing (Cold Press Shaping)   First, preheat the material in a 60–80 °C oven for 30–60 seconds, this helps shorten the subsequent thermoforming cycle and improves surface flatness. Then, place the cut sheet into the cold-press mold and apply 2–4 MPa of light pressure for 5–10 seconds. This allows the sheet to initially conform to the mold, reducing sliding or shifting during thermoforming and minimizing wrinkles.   6. EVA Thermoforming   This is the core process in producing a thermoformed EVA case. Using a four-column thermoforming machine with electrically heated platens and independently controlled upper and lower mold temperatures, the final shape of the case is essentially formed. Mold temperature: 120–180 °C, controlled by a mold-temperature machine with ±2 °C accuracy. Pressure: 10–40 MPa (adjust based on wall thickness and depth; deep cavities require the upper limit) Thermoforming time: 45–90 seconds ~45 s for 3 mm wall thickness ~60 s for 4 mm wall thickness For every additional 1 mm of EVA thickness, increase thermoforming time by 10–15 seconds Operation sequence: fast mold closing → staged pressurization → 1–2 exhaust cycles → high-pressure holding → slight mold opening for venting → cooling and final shaping.   7. Cooling and Trimming   Cooling: after the holding phase, immediately introduce cooling water or air to bring the mold temperature down to below 50–60 °C before opening the mold. Insufficient cooling may cause the thermoforming cases or boxes to rebound or the edges to warp. Trimming: depending on the thickness and hardness of the EVA composite material, you may use traditional die-cutting, a CNC punching machine, or a laser cutter to remove the excess material along the outline in a single operation. When using laser cutting, stitching guide lines, zipper channels, and other features can also be cut simultaneously, eliminating the need for secondary processing later.   8. The final step is sewing the boxes   Sew the thermoformed EVA cover or bottom case together with zipper tape and other components like webbing carry handles, add hardware such as rivets or logo patch through a pneumatic riveting machine, by here the assembling process of one pencil case or storage box is nearly finished. Last but not least, Inspection & Ticketing before packing into master cartons. Appearance check: No pressure marks, bubbles, color differences, or wrinkles. Dimensions check: Length/width/height tolerance of ±0.5 mm. Pencil case/Storage Box Performance Test: The zipper must withstand 500 times back-and-forth cycles without tooth loss or abrasion. Drop Test: Pick a few units, drop them from the set height onto a hard surface on all six faces/edges/corners, check after each drop, and confirm stored stuffs inside the boxes still work at the end. After passing inspection, pencil cases / storage boxes are packed into polybag and then placed into the master carton.     Highlights of Key Control Points for Thermoformed EVA Boxes   1.Temperature and pressure must work together: For every 5 °C increase in temperature, the pressure can be reduced by 1 MPa, and vice versa.   2.Ensure smooth mold venting: Deep cavity molds require 0.05–0.1 mm vent grooves to prevent burnt edges and reduce issues such as surface bubbling or localized delamination of laminated fabrics during forming.   3.Cooling time accounts for over 40% of the cycle: Test for the optimal cooling duration before mass production. Reducing unnecessary cooling time can significantly improve productivity.   4.Sheet moisture content >0.1% easily causes bubbles: During continuously rainy or humid days, it’s recommended to pre-dry the sheets at around 50 °C for about 3 hours before production.   5.Perform first-article inspection each shift and patrol inspection every 2 hours: Record temperature, pressure, and cooling time. Stop the machine immediately and adjust the mold if deviations are found.   By following the above procedures and parameters, a standard 5 mm wall-thickness EVA case can achieve a daily output of 1,200 pcs per machine, with a ≥98% yield rate.   Author        

1.The Development History of Dog Harnesses: From tool to Human Care.   The development of pet dog harnesses has gone through three stages. First stage:  Dog straps were originally used for working dogs such as military dogs, sled dogs, and search-and-rescue dogs, providing stable support and controlled traction for their tasks. Second stage:  As smaller dog breeds were developed, dogs gradually transitioned from working partners to family members. At this stage, dog harnesses began to be used in daily life, but the early products primarily focused on "control" and "durability." Third stage:  With the rise of health awareness, pet owners began to pay more attention to the pressure on their pets' necks. Dog harnesses evolved from mere control tools to upgrades focused on safety and comfort. In product design, emphasis was placed not only on dispersing traction pressure and reducing movement-related injuries, but also on adding user-friendly features such as reflectivity, breathability, and GPS tracking.   2. Classification of typical dog harnesses, how they are used and the relevantly suitable pets.   From crash-tested dog harness to dog vest harnesses designed to protect the trachea, different types of harnesses vary significantly in structure, force distribution, and application scenarios. Based on their design features and basic functions, dog harnesses can be categorized into the following six main types: 2.1  H-shaped dog harness Structural features: The H-style harness is made up of two horizontal straps and one vertical connecting strap, forming an "H"-shaped frame. This structure is inspired by the "H-beam" principle in engineering mechanics, offering strong tensile strength and lightweight design. It typically features leash attachment points both at the front and back. Structural Advantages: Scientific pressure distribution: The H-shaped structure distributes pulling force evenly across the shoulders, back, and chest, reducing stress on any single point. High no-pull performance: When a pet suddenly lunges, the H-shaped design acts like a “brake pad,” effectively reducing collision inertia. Simple structure: Easy to put on and take off, with minimal restriction on shoulder and front limb movement. Minimal fabric coverage: Keeps pets cool in summer and is more comfortable for sensitive skin. Wide adjustment range: Fits different body types,suitable for both cats and dogs, the top choice for an adjustable dog harness. Applications they suit： Daily walks, park strolls, and situations where no-pull performance is needed. Hiking, long-distance travel, and other outdoor activities, recommended to choose the Easy Walk Harness. Suitable Pet Types: Ideal for cats that are escape-prone, can also be used as a cat harness. Active dogs. High-energy, easily lunging breeds: Border Collies, Corgis, Alaskans, etc. Growing dogs with rapidly changing body weight. 2.2   Dog Vest Harness Structural Features: Full-wrap design: Features an integrated or large-area wrap design, increasing contact with the pet’s chest, back, and abdomen. High fit: The fabric is tailored to match the natural body curves of dogs. Structural Advantages: Comprehensive pressure distribution :The pulling force is evenly spread across large areas of the pets chest, shoulders, and back, preventing any pressure on the neck and ensuring "zero" pressure on the trachea and cervical spine. High comfort : Made with 3D breathable mesh, it keeps pets cool in the summer and can be paired with a warm lining in the winter，no pressure for extended wear, suitable as a travel dog harness. High stability :The 360° full-wrap design and wide straps ensure a snug fit, preventing fabric movement during forceful pulling. Strong anti-escape ability : The design that fits the pet's shoulder and front limb movement trajectory greatly reduces the chance of escape when the pet suddenly pulls back with force. Applications they suit： High-frequency activities like home use and daily walks (comfortable for long periods of wear). Active pets with high energy levels. Car travel (can be paired with a pet seatbelt). Crowded areas and situations where escape prevention is needed. Can be used as a puppy harness Suitable Pet Types: Breeds with sensitive skin. Suitable for puppies, senior dogs, or pets with respiratory issues. Playful, active dogs that tend to escape. 2.3  Saddle-shaped Dog Harness Structural Features: The saddle-style harness is named for its resemblance to a saddle. The overall design conforms to the pet’s body curve and covers the main pressure points on the back, with connection and adjustment achieved through 1-2 buckles，it is also a dog Harness with handle. Structural Advantages: High pet acceptance: The main pressure points are concentrated on the back, avoiding sensitive areas such as the armpits and trachea. This significantly reduces feelings of restriction and resistance, allowing most pets to quickly adapt and accept the harness. High stability : stays securely in place while walking, preventing the straps from slipping into the armpits or onto the neck and causing discomfort. Handle assistance: an integrated back handle makes it easy to help pets get in and out of vehicles, perform emergency lifting, or control excited behavior. Easy to wear : Step-in design with a buckle strap around the belly, making it quick and easy to put on in two simple steps. Usage scenarios : For pets wearing a harness for the first time. Frequent-use situations such as park walks and short outings. Professional training and correcting pulling or lunging behaviors. Post-surgery recovery, helping to avoid pressure on the neck. Suitable Pets Types: Dogs that have difficulty adapting to traditional harnesses. Medium-sized, well-proportioned dogs (such as Border Collies, Australian Shepherds, Standard Poodles, etc.) Dogs undergoing post-surgery neck recovery.   2.4   Y-shaped dog harness   Structural Features: Side Y-shape: When viewed from the side, the harness forms a clear “Y” shape. The main strap runs along the pet’s spine, while the two side straps contour precisely around the shoulders and chest, creating a stable triangular support structure. Minimal contact area: Comprised mainly of several key straps, the harness has relatively limited contact with the pet’s body. Structural Advantages: Reduced wearing burden: The strap-based design is lightweight, minimizing the load on the pet while wearing it. Cool and breathable: Large open areas allow for excellent airflow, preventing heat buildup and sweating. Ample freedom of movement: The “Y” structure avoids major mobility joints such as the shoulder blades, placing minimal restriction on actions like lifting the legs or running, and providing plenty of movement freedom.  Usage scenarios : Short, frequent activities such as neighborhood walks and quick outings. No-pull training (front-clip style). Puppy adaptation and growth transition period (can be used as a puppy harness). Light outdoor adventures (dual front and back clip design). Suitable Pets Types: Medium to small active dogs (such as Border Collies, Shiba Inus, Pomeranians). Lightweight small dog breeds. Pets that are sensitive to heat and prone to sweating.   2.5  X-shaped dog strap   Structural Features: Front and rear double X structure, the back and chest are designed with an intersecting X shape, which distributes the pulling force across the shoulders, chest, and back. Structural Advantages: Prevents neck strain: The crisscross design of the straps creates a deep V-shape that helps absorb impact when the pet suddenly moves or is pulled, reducing sudden pressure on the neck. Easier pulling: The buffer space created by the double X structure reduces the effort needed by the owner when pulling the pet. Lightweight and compact X design: The X-shaped design conforms to the body’s curves, providing a snug fit without causing excess strain on small dogs. Usage scenarios : Medium to long outdoor walks (such as dog walks or hiking in the countryside). Daily commuting (such as taking pets on public transport to and from work). Suitable Pets Types: Small dogs: Such as Chihuahuas, Pomeranians, Poodles, Yorkshire Terriers, Teddy dogs, etc.  Long-haired dogs: The small contact area of the X-design prevents the harness from tangling long fur. Medium to small cats: The X-shaped structure wraps securely, making it suitable for agile cats, Can also be used as a cat harness.   2.6  8-shaped cat harness  Structural Features: Double-ring cross structure，The design forms an "8" shape, consisting of two interconnected ring structures. Structural Advantages: Simple design: Minimalist design with only basic straps, no excessive fabric coverage. Extremely lightweight: Uses the least material compared to other harness styles, reducing the pet's burden. High efficiency for wearing and removal: Ideal for pets that dislike restriction, minimizing the time spent on getting them dressed. Usage scenarios : For daily short-distance, low-intensity walks. Suitable Pets: Sensitive pets that dislike restriction. Gentle dogs and cats that don't lunge or pull.   3.   Upgraded Design of the Dog Harness for The Specific Use   3.1  Use in Nighttime/Low-light Environments The reflective strips on the pet harness primarily serve the purpose of nighttime safety. By reflecting light, they significantly enhance the pets visibility in low-light environments. The specific uses can be summarized as follows: Protecting the pet and enhancing nighttime visibility to prevent traffic accidents: The reflective strips reflect strong light when illuminated by vehicle headlights or streetlights, making the pet visible from up to 100 meters away. Even in complete darkness, the dog will have a clear identifier, greatly reducing the likelihood of accidents. Protecting pedestrians: Prevents others from tripping over the pet or being accidentally pulled by the leash in the dark. Helping the owner quickly locate the pet: In dimly lit environments like parks or woodland paths at dusk, the reflective strips help the owner locate the pet within 3-5 seconds, preventing them from getting lost. Recommended Use of Reflective Materials: Type Features Suitable Scenarios 3M Reflective Strips Reflective distance > 50 meters, high durability Outdoor activities, working dogs 3M Reflective Strips 30% increasedvisibility, lower cost Daily city walks Reflective Ink/Print Layer Reflective effect is less than fluorescent webbing Daily city walks   3.2  Dust Protection for Outdoor Use   With the upgraded demand for pet health and hygiene, pet harnesses are now entering a more specialized phase, and outdoor dust-proof clothing has become a must-have item on pet owners' shopping lists. 3.3  Medical Assistance Early pet medical harnesses were primarily universal slings, with simple functionality mainly used for basic restraint or transportation. As veterinary rehabilitation medicine became an official discipline, people began to recognize the importance of scientific support for pet recovery. Products began to be developed through collaboration between veterinarians, rehabilitation therapists, and designers. Based on their function, support areas, and design, they can generally be divided into the following core styles:   3.3.1  Hind Leg/Rear Body Support Lift Strap Design Features: This is the most common type, with the lifting handle located on the pet's back and the main support point at the rear abdomen (near the base of the hind legs). It is usually designed in an "H" shape or with wide straps that include an abdominal support. Main Uses: Weak or paralyzed hind legs (e.g., due to degenerative myelopathy). Hip dysplasia, arthritis. Post-surgery rehabilitation walking (e.g., after cruciate ligament repair or hip joint surgery). Weakening of hind leg strength in senior dogs. Advantages: Effectively distributes the weight on the hind legs, helping pets maintain balance and walk. 3.3.2  Front Leg/Front Body Support Lift Strap Design Features: The lifting handle is located on the back, but the support straps mainly wrap around the pet’s front legs (from the armpits to the chest). Main Uses: Front limb arthritis, elbow dysplasia. Front limb fractures or post-surgery recovery. Pets with neck issues leading to front limb weakness. Pets with severely impaired balance that require simultaneous support for both the front and rear (often used in conjunction with a hind leg support strap. Advantages: Provides support to fragile front limbs, preventing the front body from collapsing 3.3.3  Full Body Support Harness Design Features: Integrates both front and hind limb support functions into one complete "vest" or "stretcher." Typically features multiple connection points and lifting handles, providing comprehensive support. Main Uses: Pets with weakness or poor coordination in all four limbs. Severe spinal conditions or post-surgery recovery. Paralyzed pets that need to be fully lifted or transferred from the ground. Long-bodied dogs (e.g., Dachshunds) with spinal issues. Advantages: Provides the most comprehensive and stable support, allowing for safe lifting of the pet as a whole. 3.3.4   Walking Assistance dog Harness Design Features: The design is lightweight and simple, typically consisting of a wide, soft strap secured with Velcro, primarily covering the abdomen and hindquarters. Main Uses: Assists with standing and walking, providing short-term support for elderly pets to rise or climb stairs. Helps pets maintain a standing position while urinating or defecating. Advantages: Easy to put on and take off, especially suitable for cleaning and care.   3.4   Sports Dog Harness   There are significant differences between competition-specific pet harnesses and everyday harnesses in terms of design philosophy, functionality, and standards. Their primary goal is to maximize the dog’s performance, ensure safety, and strictly comply with competition rules. Below are the mainstream types of competition-specific pet harnesses, categorized by major competition types: 3.4.1  Speed Competitions(e.g., Greyhound Racing, Terrier Racing) : The core of this type of harness is minimalism, lightweight design, and zero interference, much like an athlete’s running shoes. Design Features: Minimalist design: Utilizes a "Y" shape or simplified into a single strap. Lightweight material: Typically made from specialized nylon or soft leather, ensuring a very lightweight construction. 3.4.2  Pulling Competitions and Weight Pull Competitions (e.g., Sled Pulling, Weight Pulling) : The core of this type of dog straps is efficient force transmission, pressure distribution, and extreme durability. Design Features X-shaped Harness: This is the most classic and common sled dog harness. From the side, it forms an "X" shape, evenly distributing the pulling force across the chest, back, and abdomen, perfectly fitting the dog's body shape during movement. H-shaped Harness: Another common type, suitable for dogs with specific body types or working styles. Breathable, Quick-Drying Material: Since dogs sweat a lot, the material must be breathable and easy to dry. 3.4.3  Agility and flyball events : The core of this sports dog harness design is ultimate fit, zero obstruction, and ease of quick on-and-off. Dogs do not wear the harness throughout the entire competition, only when entering and exiting the arena. Design Features: Dog vest style/ H-shaped design: Extremely quick to put on and take off (typically in one second), used during dog warm-up or while waiting. No drooping or swinging parts: Ensures no interference with high-speed, precise movements such as jumping and turning. Lightweight, soft, and elastic material: Fits the body snugly without hindering preparatory activities. 3.4.4  Tracking and Search Competitions：the core features of the dog harness are durability, clear grip points, and the ability to connect a long leash. Design Features: Vest-style with Sturdy Handle:  A strong handle on the back to allow the handler to briefly assist or control the dog in complex terrains. Multiple Leash Attachment Points: D-rings on the chest or back to connect tracking leashes of varying lengths. Durable and Tear-resistant: Designed to work in environments like brush or wilderness areas. Integrated GPS Locator Attachment: For long-distance search competitions. 3.5  Swimsuit / Life Jacket With the popularity of family swimming pools and the increasing number of water activities involving pets (such as boating and beach trips), the risk of pet drowning has started to attract attention. The initial "life-saving" concept was very simple, with owners possibly using old clothing or foam materials to create makeshift floatation devices for their pets, which were the earliest forms of life jackets. With the rapid development of the pet industry, modern pet swimsuits/life jackets have now evolved into products that combine safety protection, functional assistance, and fashionable expression. Design Features : Made with high buoyancy foam materials, bright-colored waterproof fabrics, sturdy handles (for rescue), and adjustable straps. Dog Life Jacket:Core Purpose: Prevent drowning and ensure water safety.Applicable Scenarios: Boating, sailing, kayaking, white-water rafting, deep water beach areas, and any other water activities with drowning risks. Dog Swimsuit / Functional Swimwear:Core Purpose: Functional protection and assistance.Applicable Scenarios: Daily use in swimming pools, summer cooling, and winter warmth   3.6  Outdoor Raincoat   The early form of pet raincoats dates back to the 19th century. The first pet raincoats were mainly adapted from human clothing, focusing on basic waterproof functionality. Modern pet rain gear, however, has evolved from a simple rain protection tool into a professional piece of equipment that integrates protection, health, safety, and convenience. It has become an essential item in the refined pet care scene. Core Technologies and Features: 1.Waterproof and Windproof: The fabric surface is coated with TPU, PU, or PVC waterproof layers, creating a lotus-leaf-like water-repellent effect, with a waterproof rating generally exceeding 3000mm. High-frequency seamless welding technology, combined with heat-sealed tape treatment, prevents rainwater from leaking through needle holes. The windproof layer uses tightly woven fabric, effectively resisting cold wind. 2.Comfort and Convenience: Detachable inner layer design: Breathable mesh fabric for summer use and a warm liner for winter, adapting to different seasons. Velcro or buckle design at the abdomen: Allows for easy wear without having to slip it on from the legs; the raincoat can be worn by simply putting it on from the back down in 3-5 seconds. 3.Safety : Reflective strips on the main seams, with bright colors such as yellow and orange, to enhance visibility and safety in overcast or rainy weather. For hairless dog breeds, the raincoat helps prevent direct contact of rainwater with the skin, avoiding bacterial and fungal growth that can cause dermatitis. Different Waterproof Ratings Correspond to Different Levels of Rain Protection. Below are the Recommended Usage Scenarios for Pet Raincoats: Waterproof Rating Corresponding Common Fabrics Usage scenarios Entry-Level: ≥3000mm Polyester+PU  Light to moderate rain, daily walks with pets Protection Level: 8000~10000mm Polyester + TPU  Heavy rain, long outdoor excursions Super-Strong Level: ≥15000mm Taslan + Double-layer TPU (inner lining coating + surface coating) Torrential rain, extreme rainy weather In conclusion, there are various styles of dog harnesses available, and we hope the above introduction helps you in choosing the right harness for your dog. Of course, you can also have one custom-made according to your specific needs, such as Tactical Dog Harness, Service Dog Harness, Large Dog Harness, Dog Harness with Handle, Dog Harness with Name, Padded Dog Harness, Adjustable Dog Harness, and more. nbsp; 4. Key Features to Consider When Customizing a Dog Harness:   Customization Dimensions Core Parameters Implementation Methods Size Head circumference, chest circumference, back length A well-fitting harness should sit snugly on the body without rubbing the skin or restricting movement. You should be able to easily fit two fingers between the harness and your dog's body in any gap. Main Material polyester, non-woven fabric, leather polyester materials with strong wear resistance are preferred. Some can be mixed with plastic materials that are easy to clean and heat resistant. Internal and External Materials Inner fabric, PE material, cotton, silk fabric It is recommended to use cotton for the inner fabric and PE materials for the outer layer to reduce the impact and improve comfort during wear. Internal and External Materials Inner fabric, PE material, cotton, silk fabric It is recommended to use cotton for the inner fabric and PE materials for the outer layer to reduce the impact and improve comfort during wear. Handle Design Single handle, double handle, no handle The single-handle design is more ergonomic and suitable for long periods of use, especially in certain specific scenarios. D-ring & Connecting Points Connecting points between D-ring and positioning holes The use of high-quality materials is required for the D-ring to ensure that the connection is stable and safe. The D-ring must also meet safety standards and be secure. Wearing Mode Set type, card handle, walking mode The set-type combination of card and adjustment functions is commonly seen in H-shaped models. It is more sensitive to the user's head design and gives the impression of being more compact. Line Addition Work Line type, key connection points It is recommended to use the tail dragon line, especially paying attention to the important connection points between the D and the line, which must be carefully installed to enhance product durability. Safety and Light Reflection Reflection, body identification Based on setting position, consider adding more light reflection parts to improve night visibility, thus increasing safety; also reduce the risk of damage to objects due to hanging.   5. Testing Standards for Pet Chest Harnesses   Although considered "pet supplies", the U.S. Consumer Product Safety Commission (CPSC) categorizes these items as "consumer products." Particularly for those designed with cartoon patterns or small accessories, the CPSC mandates compliance with children's product standards. Therefore, if a pet chest harness product is sold in the U.S. market, it must meet the safety standards of CPSIA and ASTM F963. The specific requirements include physical testing, chemical testing, tracking label compliance, and more. 1.Physical Test: Tensile Strength Test for Dog Chest Strap (under ASTM F963 regulation): The chest harness must withstand at least 3 times the pet's weight. For example, for a 5kg dog, the chest strap should be able to handle a tensile force of ≥15kg. Impact Resistance Test for Dog Leash Snap Hooks (under ASTM F963 regulation): If the snap hook is metal, the static tensile test should be ≥1350N. Flame Retardant Test (under 16 CFR 1610 regulation): For non-textile materials, the burn rate should be ≤ 0.1 in/s to pass. If it's textile material, the standards are: Plain-surface fabric: Flame spread time ≥ 3.5 seconds Raised-surface fabric: Flame spread time > 7 seconds, both of which are compliant. 2.Chemical Test: All contactable parts must have a lead content ≤ 100ppm. Fabrics, linings, and plastic components must be tested for the 8 phthalates (referred to as 8P), with each phthalate having a limit of ≤ 1000 mg/kg (0.1%). The 8P substances are DEHP, DBP, BBP, DINP, DIBP, DPENP, DHEXP, and DCHP. Metal components with accessible coatings must meet heavy metal migration limits, specifically for 8 heavy metals. For dog chest harnesses, the focus is on Cadmium (Cd) and Lead (Pb). The required migration limits are: Cd ≤ 75,Pb ≤ 90, which is considered a compliant product. 3.Label Instruction Requirements: The label requirements are divided into mandatory federal regulations and non-federal regulations, the latter of which may apply when selling platforms such as Walmart or Amazon list the product for sale. Permanent Tracking Label: This is a mandatory requirement under U.S. federal regulations. The product label must include: Manufacturer's name, Manufacturer's address, Date of manufacture, Batch Number, Material information. Country of Origin Label: This is also a mandatory requirement under U.S. federal regulations. The product and its retail packaging must clearly indicate the country of origin. Product Warning Label: While not mandatory, it is recommended that brands include related content on the Washing Label, especially if the product is a corrective chest harness.   If the chest harness is a corrective type, it must also comply with FDA testing requirements.

With a deep-rooted understanding of user requirements developed over years, innovative materials paired with intuitive and functional design, we aim to help brands create more professional and distinctive product lines. This article will give you a comprehensive overview of the main types of bike bags, along with practical customization suggestions to support your brand in developing products with greater performance and differentiation. I. Type of Bicycle Bags and Where They’re Used   Bike bags come in a wide variety of categories. Different styles vary in capacity, mounting methods. The following overview focuses on functionality based on bike structure to help you understand the most common types of bike bags.   1. Riding-Carry Bags on Cyclists: Provide riders with a convenient, safe, and comfortable way to carry their belongings during cycling.   1.1. Cycling Backpack Specifically engineered based on cycling posture, cycling backpacks typically feature a back-hugging ergonomic structure, breathable back panels, and stable shoulder strap systems. They maintain excellent fit and comfort during high-speed or long-duration rides, ideal for outdoor cycling activities such as weekend rides.     1.2. Bike Backpack / Bicycle Backpack Unlike a cycling backpack, this option prioritizes volume and all-round utility, giving riders adaptable, roomy storage for everyday commutes, mixed-surface adventures and casual spin. Its sleek, everyday look also makes it the go-to “one bag that does it all” for riders on and off the bike.     1.3. Hydration Pack Designed for off-road cycling, mountain biking, and long-distance training. These packs include a replaceable hydration bladder inside and a drinking tube for hands-free hydration. A well-designed hydration pack further enhances back ventilation, tube hygiene, shock-absorption, and stability, ensuring higher efficiency and safety on challenging terrain.     1.4. Waist Pack / Hip Pack Known for being ultralight and securely fastened around the waist, waist packs are widely accepted by MTB riders and off-road cyclists. While compact, they are sufficient for carrying essentials such as tools, energy gels, and mobile phones.  High-quality waist packs often include multi-layer compartments, water-repellent fabric, and padded waist support to ensure stability during riding, not easily move around.     1.5. Arm Bag / Wrist Bag These small fitted pouches attach to the arm or wrist and are used for storing small items like mobile phones and cards. To ensure easy access during riding and minimal restriction on movement, such bags often require optimized structural design such as elastic arm straps, superior breathable materials, and touchscreen-friendly transparent windows.     2. Riding-Carry Bags installed on bikes: essential components for carrying Bikepacking Gears   Driven by the boom in multi-day, off-road expeditions, riders now treat on-bike mounting bags as core kit of professional cycling equipment. Unlike traditional rack panniers, today these bags emphasize light-weight design, zero-bounce or sway when riding, and a snug fit to the bike frame, keep everything planted when the trail turns ugly.   2.1. Bike Frame Bag / Bicycle Frame Bag Frame bags are typically triangular and mounted along the top tube within the frame triangle area. Depending on the bike’s geometry, they can be customized as half-frame or full-frame bags. As the central storage area for long-distance cyclists, frame bags are commonly used to carry tools, food, rain covers, power banks, and other essentials.     2.2. Top Tube Bag / Fuel Bag Mounted on the top tube of the frame triangle, top tube bags allow riders to slow down slightly and access items without stopping. They are one of the most common “fuel station bags” used in triathlons and long-distance cycling.     2.3. Bike Handlebar Bag Located at the front of the handlebars, handlebar bags range in size from small 1L pouches to large 10–20L cylindrical bags capable of holding a sleeping bag or down jacket. Every extra liter rewrites the design and construction of the handlebar bags, the little ones race to shave grams and open with one hand; mid-size gain panels and side pockets so nothing swims free; the big ones turn to architecture--stiffer bases, lower centers of gravity, compression straps, removable covers and so on.     2.4. Stem Bag / Feed Bag A small cylindrical side bag mounted between the handlebar and the stem, allowing riders to grab items one-handed while riding.     2.5. Down Tube Bag Attached to the underside or outside of the down tube, usually in a slim, elongated shape to grip the tube securely. Commonly used for carrying repair tools, spare tubes, CO₂ cartridges, and mini pumps.     2.6. Bike Saddle Bag / Seat Pack Normally put behind or beneath the seat, saddle bags come in a wide range of forms—from tiny repair pouches that hold only a spare tube to large 10L seat packs for long-distance touring, similar in concept to handlebar bags.     2.7. Fork Bag / Cargo Cage Bag Clipped on both sides of the front fork using a cargo cage, these bags typically feature adjustable straps or a roll-top closure, allowing capacity to expand from 1L to around 5L. They are perfect for family riding on weekends as well as multi-day adventures with friends.     2.8. Bikepacking Full Set—A combo of above bike bags A complete bikepacking kit composed of a frame bag, top tube bag, handlebar bag, saddle bag, fork bags, and other accessories, built for anything from a long weekend to a full ten-day tour.     3. Rear Rack Storage Bags: Pairing Carry Space with Real-World Function   3.1. Bike Pannier Bag Pannier bags are typically a pair of symmetrical large bags that hang over both sides of the rear rack. They offer substantial storage space, making them ideal for long-distance touring or delivery services. These bags are usually made from highly waterproof materials.     3.2. Bike Rack Bag Often described as a compact version of pannier bags, rack bags sit directly on top of the rear rack. They feature a central or top opening, making it extremely easy to quickly access and organize items inside.     3.3. Bike Trunk Bag Functionally similar to pannier bags and rack bags, the most noticeable difference lies in its trunk-like shape. As the name suggests, the bag is often built at a more rigid shape like cargo box, capable of carrying a wide range of items. A lot of times, they are made from fully water-proof fabric such as coated nylon or PU, then sealed with heat instead of stitches, so every seam stays dry when the sky opens up.     4. Transport & Protection Gear Bags   4.1. Bike Travel Case / Bike Case Bag Designed for long-distance travel or cycling events, these cases are used for checking in a fully assembled bicycle. They typically include: EVA or PC/ABS hard shells Internal stabilizing fixtures Impact-absorbing foam Detachable wheels Because these products require structured modeling, mold development, and system-level engineering, both development cost and complexity are relatively high.      4.2. Soft Bike Bag Soft bike bags focus on portability, nicely fit for car-trunk transport, short trips, weekend races, or everyday storage. Compared with hard-shell cases, they do not require mold development and can be folded for compact storage, an easy pick for laid-back riders and city spinners.     4.3. Other Sub-Categories Related to BIKE BAGS   4.3.1 Tools and Maintenance Bags these bags are designed to organize essential repair tools and spare parts at home such as Tool Roll Bag, Tool Pouch, Spare Tube Bag Pump Pouch, Tool Pod etc. Both small enough to vanish inside your frame bag, yet big enough to save the ride when things go sideways miles from home.     4.3.2 E-bike Carrier Bags E-bike bags are designed to protect batteries, controllers, and other electronic components from vibration, moisture, and heat. They often feature reinforced padding, waterproof fabrics, and secure mounting systems. These bags help riders safely manage the additional accessories required for electric bicycles. Specifically speaking, they are Battery Bag, Controller Bag, and Charger Bag.     5. Kids’ Cycling Bags   Kids’ bike bags strip every extra gram, built feather-light so little riders barely notice they’re there. Vibrant colors, easy-to-use designs, help young riders carry snacks, toys, and small personal items. Most come splashed with hi-visibility reflective badges and rounded, bump-soft edges, all wrapped in fun prints and toy-bright shapes that make kids want to ride just to show them off.    Just like the grown-ups, kids get their own tiny versions--Kids Handlebar Bag, Kids Basket Bag, and Little Top-Tube Pockets made small for small riders.     II. How to Choose the Right Bike Bag Based on Riding Scenarios   The following recommendations can help brands better define their product matrix during development:   1. Urban Commuting & Weekend Family Rides   Recommend: Cycling backpacks, rear rack bags, handlebar bags Feature Focus: Lightweight, clean aesthetic, stylish appearance, water-repellent   2. Long-Distance Touring   Recommend: Frame bags, pannier bags, trunk bags, handlebar bags, full bikepacking sets Feature Focus: Large capacity, abrasion-resistant and dirt-resistant   3. Off-Road / Adventure Riding   Recommend: Frame bags, saddle bags, waterproof handlebar bags Features: Reinforced structure, stable and sway-free, fully waterproof   4. International Races / Airline Transport   Recommended: Bike travel case / bike case bag Features: Impact-resistant, comprehensive protection, high safety level     III. Six Key Elements to Think When Customizing Bike Bags   As a professional manufacturer, we have summarized the six most critical elements for buyers and brands when developing cycling bags.   1. Fabric Selection: Lightweight and Durable   Commonly used materials include: Ripstop nylon TPU composite fabric 1680D ballistic nylon High-density Polyester     2. Waterproof Performance of all materials on the bike bags:   Factors affect waterproof result include: The water-repellent treatment level of the material itself The type and grade of PU/TPU coating applied to the material Seamless heat-sealing processes, such as high-frequency welding or ultrasonic heat pressing Waterproof zippers     3. Structure and Stability of Bike Bags During Riding   During cycling, bike bags are subjected to bumps, shaking, and pulling forces, reinforced stitching is a must for such bags, therefore: Key stress points should have bar tacks or extra stitching Large-capacity bags need anti-sway structures Pannier bags require additional reinforcement at the bottom and sides     4.
