Our expandable under-seat carry-on is an extremely versatile bag that starts off as a small easy-to-store pouch, and opens to become a 4-wheeled carry-on that slides comfortably under the airplane seat in front of you. Need more space? No problem! Your under-seater expands a full 5" upwards, to become a full sized TSA approved carry-on! An extra-deep packing cube is included, so you can pack your clothes in the cube, and still have plenty of room for your other carry on items.
