Deuter Zugspitze 22 SL rucksack is an ideal companion for day hikers who want to be versatile with maximum ventilation. The backpack provides increased performance thanks to the Deuter innovative Aircomfort carry system. At the heart of the Aircomfort system is its flexible spring steel frame. It is extremely durable, provides stable tension for the airy back mesh and creates the ventilation space between pack and the wearer´s back for the moist, warm air to dissipate - thus, providing maximum ventilation. In addition, the Aircomfort carry system provides shoulder straps, continuously adjustable chest strap, and waist belt and hip pads modelled to the shape of the pelvis in order to increase the comfort and to secure the fit. There is special compartment in the inside of the backpack to keep your valuables safe, elasticated inner compartment for storing wet/sweaty clothing, water reservoir, etc. and spacious lid compartment. The double lid buckles allow extra gear to be securely stored under the lid.
