Introducing the Deuter Race Exp Air Backpack, the lightweight road runner amongst Deuter bike backpacks with plenty of space. When every gram counts to gain some speed, you don’t want your backpack weighing you down with extra drag, therefore it is as light as a feather. It features the compact secure fit given by the Aircomfort Flexlite back panel system, providing ventilation during sweat-provoking ascents. The innovative mesh back system combines maximum ventilation with minimal weight through its highly elastic frame construction. It enables the free range of motion necessary on a bike.
