Ultra-lightweight yet durable bike backpack that offers excellent comfort at a low weight. The Deuter Aircomfort back system, specifically designed for cycling, features a centrally divided mesh back panel that ensures even less of the backpack rests directly on your back, creating more space for a natural spine position while seated. The airy mesh hip fins, perforated shoulder straps, and back padding provide 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.
