Our unique Airstripes System takes care of that and offers effective ventilation. It consists of two contoured, air-channelled foam profiles that are covered with a highly breathable Wide AirMesh lining. The reduced contact surface results in an optimized fresh air circulation. Also, the pack's load is kept close to the body and thus won't throw the rider off balance. THE RESULT: The minimal contact surface area of the profiled Airstripes allows free air circulation over 80 % of the back, while still providing a secure, compact fit.
