The optimized positioning of the seams provides extra comfort by minimizing friction and pressure points in the shoulder straps, for example. And thanks to the revised BRACE LINK, the straps adapt even better to the individual shoulder anatomy of the wearer, minimizing the stress on shoulders and back. This little power pack is additionally equipped with the following clever features: TOOL COMPARTMENT, HYDRATION SYSTEM COMPARTMENT, COMPARTMENT FOR GLASSES, EMERGENCY PLAN, HELMET HOLDER and SIGNALING WHISTLE.
