A soft sided pet carrier can make trips to the vet, weekends away, and some in-cabin flights easier for small dogs and cats. But two carriers that look almost identical online can perform very differently once a pet is inside.
The best carrier is not simply the lightest, cheapest, or most stylish. It should give your pet enough room, stay ventilated, close securely, support its weight, and suit the way you actually travel.
Quick answer: Before buying a soft sided pet carrier, check its internal fit, mesh ventilation, zipper security, base support, frame stability, cleaning options, carrying comfort, and travel compatibility. For air travel, always check your specific airline and aircraft requirements before booking.
Soft-Sided vs. Hard-Sided Pet Carriers: Which Is Better?
Both styles can be useful. The right choice depends on the animal, the trip, and the carrier’s construction.
| Factor | Soft-sided pet carrier | Hard-sided pet carrier |
|---|---|---|
| Everyday handling | Often lighter and easier to carry | Usually bulkier and more rigid |
| Storage | Some designs fold down when empty | Typically takes up more space |
| Ventilation | Usually uses mesh panels | Usually uses molded vents or metal doors |
| Structure | Depends on its base and frame design | Maintains its shape more consistently |
| Cleaning | Removable pads may be washable; fabric body may need spot cleaning | Hard surfaces can often be wiped down |
| Cabin flights | Frequently used for under-seat travel when airline rules allow | Acceptance depends on dimensions, airline, and aircraft |
| Cargo travel | Do not assume a cabin-style fabric carrier is suitable | Airlines commonly require a compliant rigid kennel for cargo transport |
Choose a soft-sided carrier if you need a portable bag for routine outings or eligible in-cabin travel and your pet is comfortable inside it. Consider a more rigid carrier when shape retention, heavy wear, or the animal’s behavior makes that a better fit.
1. Start With Your Pet’s Actual Size, Not Its Weight Alone
A listed weight limit tells you something about load capacity, but it does not tell you whether a long-bodied cat or tall small dog can sit comfortably.
Measure your pet while standing:
- Length: from the nose to the base of the tail.
- Height: from the floor to the highest point of the head or ears, as applicable.
- Body width: at the widest point.
Then compare those measurements with the usable internal dimensions, not just the advertised external length, width, and height. A thick pad, rounded corners, or a flexible top can reduce the room your pet actually has.
Your pet should be able to turn around and settle in a natural position without being squeezed. If you are shopping specifically for a flight, see our pet carrier size and airline limits guide before choosing a size.
2. Look for Ventilation on More Than One Side
Mesh panels allow air to move through a fabric carrier and let your pet see its surroundings. A single small mesh window may not provide the same airflow as well-positioned panels on several sides.
Check that:
- Air can circulate when the bag is carried in its normal position.
- Mesh is tightly attached along its stitched edges.
- Openings cannot be forced wider by scratching or pushing.
- The carrier is not covered by luggage, blankets, or another bag during use.
The American Kennel Club’s carrier guidance identifies mesh ventilation as an important buying feature. For short-nosed breeds or pets with breathing difficulties, consult a veterinarian before travel; these animals may face additional risks, especially when flying.
3. Test the Zippers and Every Opening
A carrier that is easy to open is convenient for owners—but it must also stay closed when the pet moves or scratches.
Before purchasing, check the top and side openings. Look for smooth-running zippers, strong stitching at the ends, and pulls that do not separate under normal use. A zipper-locking feature or other secure closure can be helpful for determined escape artists.
Top entry can be useful for gently lowering a reluctant cat into the bag, while side entry may make it easier for a confident pet to walk inside. Neither design is automatically better: the quality of the closures matters more than the number of doors.
4. Check the Base: Soft Sides Should Not Mean a Sagging Floor
One of the easiest weaknesses to miss in product photos is the bottom panel. When a carrier sags under the animal’s weight, the floor may feel unstable and the sides can distort.
Look for:
- A reasonably firm, level bottom insert.
- A removable comfort pad that sits flat.
- Reinforced attachment points for handles and shoulder straps.
- A base that stays supported when the carrier is lifted with an appropriate test load.
For pet brands designing a new model, bottom-board thickness, board material, and the way the board is secured should be specified during sampling—not left as an unmeasured detail.
5. Make Sure the Frame Keeps Its Shape
A soft sided dog carrier or cat carrier should have some flexibility, but it should not collapse onto the pet during normal use. Check the roof and sidewalls with the bag loaded to a safe, representative weight.
Some designs use reinforced piping, a structured rim, or an internal support frame. Those details can improve shape retention, but they also influence weight, foldability, and cost.
Important: A bag that compresses to fit beneath an airplane seat is not automatically suitable for that seat. Your pet must still have appropriate room, and the airline must allow the carrier on the specific flight.
6. Choose Easy-to-Clean Materials
Accidents happen, especially during long journeys. A practical design separates the features that need frequent washing from those that do not.
Useful details include a removable pad, a wipe-clean base liner, and fabric that can be spot cleaned according to the manufacturer’s instructions. If the listing says machine washable, check whether it refers to the whole carrier or only its removable mat.
Do not assume a water-resistant outer fabric means the entire carrier has a leak-proof bottom. Those are different construction claims.
7. Check Carrying Comfort for the Human, Too
A carrier may feel comfortable when empty and quite different when holding a pet.
For longer walks through airports or train stations, consider a padded shoulder strap, comfortable hand grips, balanced strap placement, and secure hardware. Some models include a luggage-handle sleeve; verify that it fits your suitcase handle and remains stable when used.
When choosing between a handheld bag and a pet backpack, think about your pet’s position and the kind of movement involved. A backpack is not automatically more comfortable for the animal simply because it is easier for the owner to carry.
8. For Flying, Check Airline Rules Before You Buy
Many shoppers search for an airline approved pet carrier, but that phrase is not a universal certification that guarantees acceptance on every aircraft.
Airlines set their own policies for in-cabin pets, including carrier size, under-seat placement, ventilation, leak resistance, and the pet’s ability to move. For example, American Airlines recommends soft-sided carriers that can fit beneath the seat without excessive collapse. Delta Air Lines also directs passengers to check flight-specific requirements.
Before purchasing a cabin carrier:
- Confirm that your airline permits your species and pet on the route.
- Check the allowance for your specific aircraft and ticket.
- Measure the fully assembled carrier including protruding parts.
- Confirm that your pet fits comfortably inside the usable space.
- Reserve your pet’s place with the airline if required.

For Pet Brands: Turn These Features Into a Reliable Product Specification
If you sell pet accessories under your own brand, the same buying checklist can become an OEM/ODM development checklist. The difference between a promising sample and a consistent bulk order is often in details that never appear in a product title.
For a custom soft-sided pet carrier, define the following before requesting a final quotation:
- Target customer and use case: cats, small dogs, vet visits, road trips, or cabin flights.
- Dimensions: internal usable size, external assembled size, and measurement tolerances.
- Materials: outer fabric specification, mesh construction, lining, and removable pad.
- Support structure: bottom insert and frame type, including loaded-shape checks.
- Security: opening design, zipper and slider requirements, hardware and stitch reinforcement.
- Branding and packing: logo method, labels, retail packaging, and carton requirements.
- Quality checks: sample measurements, carrying-load checks, zipper operation, and visual workmanship standards.

Frequently Asked Questions
Are soft sided pet carriers safe for cats?
They can be appropriate when the carrier fits the cat, closes securely, allows airflow, and retains enough structure during use. Cats that scratch, chew, or force openings may require a different style or stronger construction. Help your cat become familiar with the carrier before travel; the American Veterinary Medical Association recommends acclimating pets ahead of trips.
Is a soft sided carrier better for airplane travel?
A soft-sided model can be convenient for eligible in-cabin travel, but there is no universally accepted size or design. Airline rules, route restrictions, aircraft layout, and your pet’s fit all matter. Verify these details with the airline directly.
How do I know what size soft sided pet carrier to buy?
Measure the pet’s length and height, then check the carrier’s usable internal dimensions. Weight capacity alone is not enough. For flying, work within both the pet’s comfort requirements and your airline’s specific carrier limits.
Can a soft sided pet carrier be used in a car?
It can transport a pet, but do not assume every fabric carrier offers crash protection. Follow the carrier’s restraint instructions and use a product appropriately designed and tested for car safety if crash protection is the goal.
