The Airstripes back system with a low back contact area and large ventilation channels, along with the perforated shoulder straps and hip fins, ensures optimal air circulation, close-to-body weight distribution, and a compact fit in any terrain. The flat lid design provides ample headroom, even when wearing a helmet. Thanks to attachments on the shoulder straps, the carabiners of the via ferrata set are always within reach. Additionally, equipment and materials are quickly accessible thanks to the large zipper front access and side pockets.
