The Supersafe 10.2mm rope was the result of Mammuts goal to reduce climbing accidents by making the safest rope in the world. Thanks to its Teflon-coated fibers, which reduce internal friction, the Supersafe was one of the first ropes to ever pass the UIAA Sharp Edge Resistance test. Most standard ropes part like dental floss when they are subjected to this extreme test. The ones that do pass are usually so stiff that they handle like tugboat cables. The Supersafe passed with flying colors and retains excellent handling qualities for fast clips and easy belaying. Its also Superdry coated, so it will not loose strength from absorbing water. Two of the most common climbing accidents occur when rappelling or lowering off the end of a rope. To prevent this, you can get the Supersafe with an optional Triodess pattern that changes 5 meters from each end so youll know youre about out of rope before its too late.
