The All-In-One is our pick for a small pet carrier that changes with the journey: carry it by hand, over a shoulder or as a backpack, then open the expansion window for extra room. The washable memory-foam pad and multiple compartments make it a more organized travel bag. maxbone lists a 20 lb pet limit, while the carrier itself weighs 4 lb; check your pet's measurements and the airline's exact rules before a trip.
Why we like it
- Three carry modes make the bag adaptable to different journeys.
- The expansion window and removable pad add useful travel details.
- It folds down for storage between trips.
Keep in mind
The carrier weighs 4 lb before adding your pet. Airline acceptance depends on the specific airline, aircraft and route, so confirm the current dimensions and requirements directly before booking.

Switch the way you carry it
The bag can be carried by hand, over the shoulder or as a backpack. That flexibility is the main reason to consider it when a trip involves moving between a car, a station or a walk.
Room to settle in
The expansion window opens additional space, and the removable memory-foam pad can be washed. Multiple compartments keep small travel items together without placing them loose inside the pet's space.

The carrier measures 18.5 × 11 × 9.5 inches and weighs 4 lb, with maxbone listing a 20 lb pet limit. Airline rules vary by airline and route; confirm the carrier's dimensions and your pet's acceptance directly with the airline before travel.
