Ultra-light yet durable bike backpack with excellent comfort at a low weight. The Deuter Aircomfort back system, specially designed for cycling, features a centrally divided mesh back panel that reduces direct contact with the back and creates more space for a natural spine position while seated. The airy mesh hip fins, perforated shoulder straps, and back padding ensure maximum air circulation and a secure, snug fit. This climate-neutral, PFC-free mountain bike backpack is made from bluesign-certified, 100% recycled materials and components produced using environmentally friendly, resource-efficient manufacturing processes.
