1 The strong Aircomfort mesh provides comfort and top class ventilation: the hot air dissipates freely from three sides.

2 Ventilated pads made of bilaminate foam (AC Lite series, Zugspitze 24S and 28L), or Contoured hip belt with ventilated pads (Gröden 30 S and 35 L, Gesäuse 32 S and 40 L) for ideal carrying comfort, and stability.

3 Durable spring steel frame provides a flexible and light structure, and applies tension to the mesh.

4 Contoured, padded shoulder straps with MeshTex.

Put an end to the sweaty back syndrome! This system keeps the packsack from coming in direct contact with the wearer's back. Moist air can freely escape through the three-sided ventilated system preventing heat build-up. Test results from Germany's Hohenstein Research Institute show that the Aircomfort system reduces perspiration up to 25%. Additional padding at the shoulder blades and hip increase the carrying comfort.
