Deuter Aircontact System

  • Stabilizer straps allow optimal positioning of the backpack. These are easily repositioned on the shoulder straps using a Triglide buckle. Aircontact models about 50 + 10 SL sizes also have two different fixing points, depending on the back length setting, in order to optimize the load adjustor strap angle.
  • Breathable padding with special ventilating hollow chamber foam; with every movement, a pump effect circulates air through the breathable Aircontact cushions of this direct body contact system. Extra air channel ventilation between the back cushions is very effective.
  • The anatomically shaped hip fins are made from multiple layers. The inner side has a layer of soft foam with 3D AirMesh lining for heightened comfort. The firm foam on the outside is modelled to the anatomic shape and transfers the load to the hips. Side compression straps on the fins regulate the load and increase stability. On the compact ACT Lite fins this bilaminate construction is perfectly balanced between weight reduction and load transfer ratio. Aircontact models designed to carry heavier loads, maximize stability and load transfer thanks to the additional synthetic reinforcement in between foam layers.
  • Head molding provides freedom of head movement. Effective on models Aircontact 50 + 10 SL and up.
  • Countoured shoulder straps with 3D Air Mesh lining.
  • Vari Quick system for easy adjustment to any back length
  • The anatomic profiled X-Frame offers a balance of torsional rigidity and flexibility to follow your body movements, and transfers weight through it's perfect back fit.
