The Airstripes back system with low back support and large ventilation channels as well as the perforated shoulder straps and hip fins ensure optimum air circulation, body-hugging weight distribution and therefore a compact fit in any terrain. Thanks to attachments on the shoulder straps, the carabiners of the via ferrata set are always within easy reach. In addition, equipment and materials are quickly to hand thanks to the large arched opening with zip, elasticated front pocket and side pockets.
