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