The ultimate ultralight cord for ski mountaineering and crevasse rescue.

When you are moving fast and light through heavily glaciated terrain, carrying a full-weight dynamic rope is not always practical. The Petzl RAD LINE 6 mm (Rescue And Descent) is an innovative, hyper-static cord designed specifically to meet the demands of ski mountaineers and alpine minimalists. Engineered with a specialized blend of high-modulus polyethylene (HMPE) and aramid, it boasts an exceptionally low static elongation and a rough sheath texture for maximum control. Whether you are building a complex mechanical advantage system for a crevasse rescue, rappelling into a steep couloir, or roping up for rolling glacier travel, this highly compact cord provides the critical safety margin you need without weighing down your pack.
