The Trail Force 5 has been completely updated in collaboration with Franco Collé and Giuditta Turini, the ‘golden couple’ of the Italian trail. It is a hyperlight form-fitting running vest that has been purpose built for sky running races and light and fast missions where having the right gear and enough hydration is critical, but not knowing you’re carrying it is essential. The vest is formed with enough material to create enough surface contact with the body to limit movement while running. The main compartment and all accessory compartments feature compression materials to limit load shifting. Soft, ventilated, moisture-wicking 3D mesh combines with soft edging material anywhere the vest comes in contact with the body for superior comfort even on bare skin. The main front closure combines with elasticized adjustability on the sides to fine-tune the fit. The innovative trekking pole carrying system is derived from the X-Press ski carrying system on our ski mountaineering backpacks. It allows the poles to be attached and removed without stopping or removing the pack. The system uses elastic cords that are fixed to the poles that can then be captured by a carabiner (included). Once the poles are clipped together, the carabiner gets clipped to a loop on the back left-side of the pack and then the tips of poles get captured by the X-Press strap on the right shoulder for a very secure and fast attachment.
