Lightwave Lightning Dyneema Guylines 4 pack. High-strength guylines good enough for five-season mountaineering. They are UV-resistant and absorb no moisture (so don't freeze up).
Our lightest guylines: a set of 4 weighs less than a single standard 3-mm nylon guyline! Lightning guylines consist of a Dyneema core wrapped in a polyester sheath, which combine to give a total diameter of 1.5 mm and a breaking strain of 110 kg. Each line comes with a mini-Linelok cleat for easy adjustment. These are standard issue with our hyper and ultra tent ranges.
