To be easily tolerated by the climber a climbing fall requires thwo factor: the resistance of all the elements of the safety chain (rope, carabiners, protection etc.) and their ability to absorb part of the energy released in the fall. The harness is pratically static and transmits all the remaining energy on the thighs (that absorb it well), around the waist (that absorb well enough) and on the spine where all the microtrauma add up creating permanent effects. For this Grivel has developed the GS composed of a half-shell semi hard to better distribute the forces, coupled inside with a special honeycomb materal able to absorb most of the energy without trasferring it on the spine.
Harness not included.
