Introducing Vortex SD with SamsonDry, Samson's exclusive hydrophobic coating. The lightest premium climbing line available of its size, the SamsonDry technology limits water absorption to less than 5%, keeping your line lighter and safer in wet conditions. Vortex SD meets UIAA standards, has excellent knot holding ability, works well with hardware, and is great for footlocking. It also has 25 - 30% lower elongation when used at the same load compared to ropes of similar size.
