Endowed with a tight braid and an extra thick sheath, the Blue Water Icon Double Dry 9. 1mm Climbing Rope brings a new level of durability to the world of ultra-skinny redpoint cords. As a result of seeking lower weights and smaller diameters, skinny singles have traditionally been prone to short lifespans. Thanks to the Icon's 35% sheath mass, this rope can provide the featherlight performance serious sport climbers need with reduced drag, increased abrasion resistance, and a longer lifespan.
