This back system takes the load off your back! The revolutionary X Vent Zero carrying system offers maximum control and the best ventilation with minimal contact with the back. Through two x-shaped crossed glass fibre rods the load 1 is efficiently deflected to the hips. The system is infinitely variable 2 and can be carried securely on the back if the glass fibre rods are removed. By reducing the materials used to produce them, each rucksack in this series has become a real lightweight.
