A high tech, back-free, ventilation optimized carry device for hydration and other essential needs on shorter rides. It includes enough space for a tube, some tools and a 1.5L hydration system. The Hip Pack Pro 3L also comes with a very dialed system for extra comfort: called Ventiflap, the wearer can increase the back distance for climbing and tighten it to the hip for the downhill, simply by pulling a string.
