Edelrid Swift Protect Pro Dry 8.9 mm climbing rope is versatile and lends itself very well to mountaineering and numerous other vertical activities. Swift Protect Pro Dry 8.9 mm stands out from other dynamic ropes for its extremely cut and abrasion resistant structure thanks to the addition of aramid fibers in the sock. In an alpine environment where the probability of hitting blades of rock or very rough surfaces is high, having a rope like the Swift Protect Pro Dry 8.9 can make all the difference. Lightness and manageability are given by the full dry and ThermoShield treatments. The Pro Dry allows the rope to resist dust, dirt and water. The rope is not completely waterproof but in a humid environment it will only absorb a certain percentage of water which will increase the weight of the rope by 2%.
