The X1 carrying system is specially designed for carrying heavy loads over 20 kg. The special X-shaped construction directs part of the load horizontally to the specially padded hip strap thus transferring the load from the back to the hips. This means that the weight can be transported over much longer distances. The anatomically positioned and very comfortable hip strap , the load control straps and the soft, ergonomic shoulder strap can be easily adjusted and allow the carrying system to be adapted to the perfect fit. A rubberised lumbar pad and the back padding above it with its concave shape ensure stability and that the rucksack sits perfectly against the back.
