Description

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.

On the whole, the Sterling Evolution Duetto ropes have performed beautifully; they’ve lived up to their reputation, and I would have to really dig deep to come up with more gripes than the two minor ones listed above. Half ropes are wonderful in general, and these are better than most. Though it seems like a minor point, I thought that it spoke to the rope’s handling that it was so easy to slide clove hitches when adjusting a tie-in, as well as untie knots that had tightened during a fall.

For anyone considering making the jump from singles to halves, these are a solid option—even if you never thought you’d consider switching rope brands again.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
