Comfortable carrying system with air circulation for active sports. Rucksacks that have to follow fast movement sequences are fitted with the Comfort back. The basic principle is that of the Vent back: On this light back construction, two lateral foam pads [1] ensure a pleasant level of comfort. The concave shape ensures optimum load control. Ventilation channels [2] in the middle and the air-permeable AirTex cover on the open-pored foam of the padding provide an extremely pleasant microclimate, even with high loads.
