Extremely lightweight, stable bike backpack with an excellent weight-to-comfort ratio. The bike-specific Aircomfort back system with centrally divided mesh back reduces the contact surface and provides more space for the spine, which is curved in the riding position. Mesh hip fins, perforated shoulder straps and back padding ensure maximum ventilation and a compact fit. The climate-neutral, PFC-free backpack for sporty mountain bikers is made from bluesign® certified main material made from 100% recycled fabrics and 100% environmentally friendly, resource-saving components.
