The mountains are calling! The reduced contact surface and large ventilation channels of the deuter Airstripes back system combined with perforated shoulder straps and hip fins ensure maximum airflow and even weight distribution - for a snug, secure fit over any terrain. Loops on the shoulder straps keep via ferrata set carabiners close at hand. And thanks to a wide zip around opening, elasticated stash pocket on the front and side pockets, equipment is always easy to access. deuter - Trail 25l Backpack black shale
