Packing for a weekend away, or just the commute between the office and the gym? This structured travel backpack goes from a light commute to a loaded weekend in one bag, and its dry and damp zones keep gym kit away from clean clothes. When it is not expanded it stays compact, easy to handle in a car, an overhead bin or a locker.

Sized 12 x 7.8 x 20 inches (30.5 x 19.8 x 50.8 cm), it works as a carry on backpack for short trips and as a daypack or commuter backpack for daily transport. The compression mechanism and its compact air-release tool manage space for packed items, adjustable internal and external compartments let you set the bag up the way you pack, and the structured shell keeps a defined form in transit or storage.
