Deuter Trekking Rucksacks are the easiest way to carry heavy loads, combining the backpack and your body together into almost a single unit.
This is the principle of the Deuter Aircontact system boasted by many of the Deuter range here: a body-contact system with perfect stability, exact load dispersal and effective ventilation, making Deuter one of the most respected names for trekking and hiking backpacks.
With every movement when wearing a Deuter Trekking Backpack, 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 of the Aircontact system is up to 15% less sweating with Deuter Trekking Rucksacks than with a standard trekking backpack.
