Use this tubular webbing for making your own runners or etriers, for anchoring or for use as a sling. Sewn in a tube shape and flattened out for double strength. When tying your own runners, leave at least 2 tails for safety. Ideal for tying with a water knot meant to be tightened under full-body weight. For proper instructions, consult a climbing reference, i.e. Mountaineering Freedom of the Hills.
