The Airstripes back system with minimal back contact 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 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, gear and materials can be quickly accessed through the large zipper front opening and side pockets.
