The Deuter Aircontact Lite 40 10 trekking backpack is a modern model using the Aircontact technological carrier system, which is ideal for carrying heavier loads. It consists of thick panels of specialized foam that guarantees a very high level of comfort and eliminates pressure points that are the main cause of chafing over longer distances. This foam alternately flexes and expands as you walk, forcing air to move across your back. Thanks to this, moisture and heat are dissipated much more efficiently. The shoulder straps are anatomically shaped and height adjustable, so the backpack can be perfectly adapted to the body. An important role in the carrying system of the Deuter Aircontact Lite 40 10 backpack is played by the waist belt, which carries most of the load.
