Twin and Half Ropes
The Duetto is built to be lightweight with a great hand. The smooth, abrasion resistant sheath glides over the snow and ice and through gear effortlessly. The Duetto is the half rope to turn too when you need something a little thicker than our Fusion Photon. This rope is also available in shorter lengths for alpine touring and glacier travel.
Evolution series are the original ropes that Sterling offered and are engineered for an ideal balance of diameter to weight.
