The Deuter Aircontact X 80+15 SL impresses as a versatile professional backpack with individually adjustable compression straps for flexible gear attachment. Additionally, the backpack offers extra storage space through removable hip belt pockets. A fold-out pocket accommodates a water bottle. Thanks to the VariSlide system with adjustable back length, the precisely fitting VariFlex hip fins, and the movable ActiveFit shoulder straps, the Aircontact X can be optimally adjusted to the individual size of the wearer. The large Air Spacer Mesh ensures high carrying comfort. Bluesign® (main material) This Deuter product is certified by Bluesign®. This means that production is monitored by a third party to eliminate all harmful chemicals or substances from the production process from start to finish. This benefits everyone: people, animals, and the entire planet. SL Version Since the carrying comfort of your backpack depends on back length, shoulder width, and body size, Deuter has developed specific SL models. These primarily differ in back length, as well as in the distance and shape of the shoulder straps compared to other models. Thus, SL backpacks are particularly well-suited for women and teenagers, but also for slim and shorter men.
