Originally designed for the rigors of Southern Utah's notorious sandstone canyons; this rope has become a crossover specialty for many critical industrial and military applications. A 100% HMPE core (ultra high molecular weight polyethylene) covered with a durable cabled, solution dyed polyester sheath. Small diameter, lightweight, and high strength. This rope is designed to shed water and dry quickly. Use with a Totem or Critr 2 only! Not recommended for use with an ATC style device or Pirana descender due to potential for sheath slippage around their sharp radius on long rappels.
