Product Description:
Travel in style with this U.S. Traveler Rio 2-piece Carry-On Luggage Set. It includes a 21" expandable, wheeled upright and a 14" boarding bag. Both pieces of the Rio luggage set meet the FAA carry-on regulations. You can easily slide the boarding bag over the handle of the 21" expandable, wheeled upright, making travel a snap. This US Traveler luggage set's metal hardware holds up to the rigors of the shipping process. Densely woven, 1200D polyester is very strong and keeps water from seeping in through the outside. The handle locks in place securely so you don't have to fiddle with it while you walk. A set of skate wheels make the luggage easier to transport without having to pick it up.
