Monterey Backpack Pet Carrier

A horizontal backpack pet carrier made for travel days when your hands are already full.

The Mr. Peanut’s Monterey Series Backpack Pet Carrier is designed to carry your pet horizontally on your back, giving them a more natural resting position than many vertical backpack-style carriers. Made for biking, travel, hiking, and everyday adventures, it combines backpack practicality with a soft-sided carrier design built for comfort and stability.

The Monterey includes premium auto self-locking zippers, washable nylon plush thermal comfort padding on two sides, a composite base, open-air mesh windows on four sides, and multiple travel-friendly details like a luggage band strap, seatbelt attachments, leash tether, storage pockets, and a laptop sleeve for devices under 13".

The Medium size is designed for in-cabin airline use and can lay on its short padded side for pet comfort and under-seat compatibility. The Large size is best for transcontinental and international routes only, since those aircraft typically have larger under-seat spacing than regional aircraft.

How to measure

Measure your pet while they are comfortably lying down, since this is the typical resting position during flight time. Weight alone can be misleading, so compare your pet’s actual laying-down measurements to the carrier’s interior sizing before choosing a size.

Good to know

Acclimate your pet to the carrier at home before using it for travel, vet visits, or airport days. Let them explore it as a familiar resting space so their first time inside is not during a stressful outing.

Airline under-seat requirements vary by airline, route, and aircraft. Always confirm carrier sizing with your airline before flying.
