The Petzl Nitro Shock-Absorbing Sling reduces the force on rock and ice protection to increase the chance that your tied-off blade or crappy ice screw will hold a fall.
The Petzl Nitro 3 Shock-Absorbing Stitched Sling is designed specifically to absorb shock and prevent small pieces, dubious placements or anchors from failing during a fall. Use in sketchy terrain on bad ice or rotten rock. The six-branches of webbing are folded and stitched together so the stitches will pull out under force and reduce the shock load.
Bottom Line: An extra measure of safety when you're in dicey terrain.
