The Duetto is part of Sterling's Evolution Series. The sheath and core construction has been engineered for an ideal balance of low impact force, lightweight and high fall ratings, making a very durable rope. The Duetto has a smooth sheath to cut down on rope drag either from the rock or your gear, making progress and clipping easier, and for great handling overall.
The core yarns of the Duetto have been treated to reduce moisture absorption and yarn-on-yarn abrasion. Sterling have tested ropes with and without their DryCore treatment and have found that the DryCore ropes maintained their strength characteristics and had less elongation than non DryCore ropes when wet.
Alongside the DryCore the Duetto Dry has also had its sheath treated. This protects the rope from water absorption which eliminates weight increase, risk of freezing in cold weather, and slows the wearing of the rope considerably.
The Sterling Duetto would be an ideal choice for those looking for a cragging and multipitch half rope.
