Lightwave's high-strength guylines are good enough for five-season mountaineering. They are 2mm in diameter and 3.0 metres long. They are UV-resistant and absorb no moisture (so don't freeze up). They come with a mini-Linelok adjuster.
The ultimate guylines for mountaineering and 5-season use, these consist of a pre-stretched and treated Dyneema core, wrapped in a polyester sheath, and have a total diameter of 2 mm. Our Dyneema guylines offer an incredible strength-to-weight ratio with a breaking strain of 180 kg. Each line comes with a mini-Linelok cleat for easy adjustment.
