The Airstripes back system with a low back support 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. 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 thanks to the large round arch opening with a zipper, elastic front pocket, and side pockets.
