1 The ‘pull-forward’ function makes the hip belt easy to fasten, even with even heavy loads.

2 Breathable cushion with ventilating Aircontact technology. Durable 3D Airmesh back system overall lining wicks away warmth and moisture.

3 Height adjustable load transfer straps on the shoulder straps for precision pack positioning.

4 Contoured shoulder straps with 3D Air mesh lining. Heavy duty construction with special dual layer foams.

5 Two ergonomically formed V-shape multi-chamber aluminium stays, direct part of the load from the back to the hips.

6 When fastened, the hip fins taper upwards in a conical form. The fins are concave and ultra-padded and sit perfectly on the hips. The multi-layered, PE-stiffened foam spreads the load evenly.

Heavy loads can be carried easily if the backpack and the wearer form one unit. That is where our Aircontact principle kicks in with our trekking backpacks: a body contact system with perfect stability, optimal load distribution and effective ventilation.
With every movement a pump effect circulates air through the breathable Hollow chamber Aicontact cushions to provide all-round ventilation. The special bilaminate ACT construction allows the wearer to carry the backpack close to the body but still allows for extremely good ventilation.
The result: 15% less perspiration than with a conventional Trekking rucksack . This was confirmed in a field test performed by the company Gabriel,  leistungsdiagnostic & Trainingssteuerung (performance analysis and training planning), in cooperation with the University of Erlangen.
