The Airstripes back system with a low contact area and breathable, quick-drying Air Spacer Mesh, combined with the perforated shoulder straps and hip fins, ensures maximum ventilation, good load distribution, and a compact fit on multi-day tours with via ferrata. Thanks to the attachments on the shoulder straps, the carabiners of the via ferrata set are always within reach, and the gear is well organized and quickly stowed away through the large zipper main compartment access, elastic side pockets, and separate bottom compartment.
