Thule's Subterra Carry On Spinner Bag is carry-on sized and built to fly down terminals and tarmacs, so we don't miss our epic vacation. It's a durable bag with highly abrasion-resistant 860-denier nylon and a polycarbonate frame that can take the worst that planes, trains, and automobiles can dish out. We also like how the Subterra features a divided main compartment to either separate our clean and dirty clothes or keep our clothes on one side and our partner's on the other. With oversized wheels and V-tubing telescoping handles, this is reliable, streamlined luggage for convenient travel.
