The Duetto is 8.4mm and built to be lightweight with a great hand. The smooth, abrasion resistant sheath glides over the rock and thru gear, ready to catch a fall with the least impact of our half ropes. This rope is also available in shorter lengths for alpine touring and glacier travel. Evolution series are the original ropes offered by Sterling and are engineered for an ideal balance of diameter to weight.
