Osprey Ozone Convertible (50L)

Osprey’s Ozone Convertible 50L/22" is a travelling chameleon. First, it’s a piece of wheeled luggage perfectly sized to meet the airline’s maximum carry-on size specifications. But it has a hidden backpack suspension system so you can carry on when the pavement ends. When you reach base camp, you can zip off the Ozone Convertible’s detachable daypack and keep on exploring.
