Deuter Aircontact Trekking Rucksacks are the easiest way to carry heavy loads, combining the backpack and your body together into one unit.
This is exactly what the Aircontact principle of Deuter Trekking Backpacks is about: a body-contact system with perfect stability, exact load dispersion and effective ventilation.
With every movement, a pump effect circulates air through the special breathable hollow chamber foam Aircontact cushions. The air channels between these cushions increase the ventilation effect.
The result is up to 15% less sweating with Deuter backpacks than with a standard trekking backpack.
