Unlike most skinny ropes, you can climb with the Blue Water Wave Double Dry 9. 3mm Climbing Rope as a single for single pitch routes or pair it up as a half rope for some big wall adventures. Blue Water packed as much sheath onto this rope as possible so you can climb with it as a single or a half rope, and this unique construction gives the rope incredible handling characteristics as well as a longer life. The Wave also holds a round shape throughout its life in order to ease your rope management on big walls and help you find dead spots faster. Blue Water also added a Double Dry treatment to this rope in order to prevent it from absorbing water from puddles and wet rocks.
