The core of our tent guylines is made of Dyneema, a high-tech fiber with perfect properties for guylines. Based on its mass, Dyneema's tensile strength of 200 kg/ 440 lbs is 15 x greater than steel, 5 x stronger than Nylon and 40% stronger than Kevlar. Dyneema is so light that it floats and has a high resistance to abrasion, humidity, UV radiation and chemicals.

Dyneema is static and will not stretch as wind force increases. This reduces vibration of the tent, pegs from being pulled free and damage to tent poles. It is supple enough to allow knots to be tied. Reflective thread has been woven into the the mantle to increase visibility at night.
