Deuter's Quantum 70 10 Backpack handles long trips through Asia as well as your weekend warrior excursions in the mountains. Its Aircontact SL suspension system includes a X frame for rigid support with heavy loads, Deuter's Vari Flex system for flexible mobility, and breathable padding for comfort. Vari Quick back adjustment moves the contoured shoulder straps nearer or farther from the anatomically padded waist belt to ensure a customized fit. The Quantum 70 10 is a traditional top loader, and Deuter added a U shaped front zipper for quick and easy access to the main compartment. The detachable daypack makes an excellent companion for short hikes, museums, and sightseeing. This backpack also features a rain cover that wraps completely around the backpack for use as a transport cover on flights. There are two additional compartments for sleeping bags and wet gear, and pockets inside, at the lid, and at the sides give plenty of storage for the smaller things.
