The Xpack is a handy go-anywhere travel bag for small pets. It extends outwards to allow space for your pet to move around. Made of unscratchable, waterproof, UV-protected Heavy Duty Fabric, it features claw-proof front and side windows, a sunroof, a safety leash to prevent your small pet from falling or getting out unintentionally, and an inner fiberglass frame for added rigidity when fully expanded. It can be carried as a backpack or front pack, and can be strapped to any car seat. The Xpack includes a “winter/summer” reversible comfort mat. 12"x12"x12"
