Thule Subterra Carry-On 22"
Thule's Subterra 22-inch carry-on's oversized wheels and molded polycarbonate back panel absorb bumpy terrain, and its handles made of V-shaped tubing resist flexing. But it’s the inside of the bag that's interesting. The space is divided into two oversized compartments, one with a ratcheting compression board that uses the same closure system as Thule’s hitch-mount bike racks. Click it closed, and not only does it separate clean clothes from dirty ones, but it helps you get your suitcase closed without sitting on it. A piggyback strap attachment loop lets you hook on a personal item so you can wheel that, too. [$280; thule.com]
