The revamped Deuter Aircontact 45 + 10 is a refined version of our beloved Aircontact packs. A detachable lid-to-summit pack, pivoting VariFlex hip belt and ActiveFit shoulder harness guarantees a comfortable fit for the longest hikes. The Aircontact backsystem reduces weight up to 15% without skimping on ventilation and durability while the VariQuick back length adjustment system allows for quick and easy torso length adjustment.
