The Booster III DryCoVer is a fine blend of weight, strength, handling, and running quality. This is the rope for discriminating climbers who want a slightly thicker-diameter rope that feels light and supple. Combining lightness with a reduced surface area-which alleviates rope drag-this strong rope has proved its usefulness on today's endurance routes like The Nose and Half Dome. Today, speed is of the essence and extra ounces sap strength.
