• 🐈【Extendable and Foldable】The dimensions of the backpack are 16.1'' x 11'' x 12.5''. It's a generously sized carrier designed for pets weighing up to 22 lbs. Compared to regular backpacks, it offers extra expansion space, increasing the internal room by 80% when expanded. Additionally, this carrier is foldable, taking up minimal space when not in use. 🐕【Maximum Air Circulation】The backpack's three transparent PVC sides offer a wide view and excellent light transmission for your pet, enhancing their comfort during travel. Simultaneously, it makes it easy for you to observe your pet's movements and overall condition while on the go. 🐈【Multiple Entries】The backpack's two sides, top, and back can be opened as entrances for your pet, providing four convenient ways for them to enter and exit the carrier. Additionally, the upper window allows your pet to poke their head out and savor the scenery during the journey, making it a delightful experience for both you and your furry companion. 🐈【Security】Our backpack features a lock-type zipper design to prevent pets from accidentally unzipping it. Inside the backpack, there's a lanyard that can be attached to your pet's collar, ensuring they won't accidentally fall out. The robust internal rod structure enhances the bag's stability, and the strong base prevents deformation when your pet is inside. This allows your furry friend to sit or lie down comfortably in the backpack. 🐈【Ergonomic Design】The backpack's back and shoulder straps are thoughtfully padded with honeycomb mesh elastic sponge, ensuring breathability while providing resistance to compression and shock absorption. Coupled with the chest buckle, this design effectively alleviates pressure on you during long trips, enhancing your comfort throughout the journey.
