The reduced contact area and large ventilation channels of the Deuter Airstripes back system, combined with the perforated shoulder straps and hip fins, ensure maximum air circulation and even weight distribution – providing a secure fit in any terrain. Loops on the shoulder straps keep climbing gear carabiners within easy reach. And thanks to the large zipper opening at the front, the front pocket, and the side pockets, equipment and materials are always easily accessible.
