BlueWater also raised the bar for dryness and rope longevity with our Double-DryTM treatment, which is applied to each individual fiber in the sheath and core. BlueWater Double-Dry allows just 11% water absorbtion (compared to the standard 20% - 30%) so your rope remains light and flexible under adverse conditions. Double-Dry also increases rope longevity and is an option on all BlueWater dynamic cords. The more you know about ropes, the more you'll demand BlueWater.
