Ultra-light yet durable bike backpack with outstanding comfort for the weight. The deuter Aircomfort back system, designed specifically for biking, with a mesh back panel thats split down the middle means that even less of the pack is in direct contact with the back, and makes more room for a rounded spine in riding position. The airy mesh hip fins, perforated shoulder straps and back padding ensure maximum airflow and a solid, snug fit. This climate neutral, PFC-free mountain biking pack uses bluesign approved 100% recycled body fabric, and components made using environmentally friendly, resource-efficient manufacturing practices.
