In my opinion, the best multi-pitch rope out there is Sterling’s 9.5mm Evolution Helix. The Helix, and it’s smaller sister the 9.2mm Aero both have some unique qualities that set them apart from anything else on the market and make them our go-to ropes for multi-pitch adventures. I’ll break them down into the qualities I mentioned above; durability, light weight and hand.

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.
