Anatomically formed shoulder straps with perforated foam and large-celled 3D AirMesh lining to make them airy.
Twin-frame construction gives the Aircomfort Flexlite System its special lightweight properties at the same time as guaranteeing excellent flexibility and ergonomic fit. The secret lies in the combination of complimentary round and flat spring steel frame profiles. It easily follows body movements and transfers the load perfectly to the hip fins. It also gives the back mesh a stable tensioned platform for the patented Deuter 3-sided ventilation system.
