Comfortable carrying handles and an adjustable shoulder strap. Has pockets, seatbelt straps on one side and a luggage strap on the other. Attached leash inside. Opens from 5 sides; the top, both ends, and both sides expand and can be open when expanded. The entire carrier is lined in faux fur and mesh. When not expanded the faux fur sides zip up and the expansion sides fold in and zip up. Under all of the faux fur liner is waterproof fabric.
