Osprey Ozone 22

Osprey used lessons and materials from its hardcore backpacking line to create the lightest fully-featured carry-on on the market, at a scant four pounds. "I was skeptical, but the one-bar, one-handed design works," says Dickey. "It's more like a rolling duffel and could use more compartments. This one's best for quick trips."  [$230; rei.com]
