Rope specifically for multi-pitch climbing
- use as half or twin rope
- on rock
Greater longevity and ease of use:
- UltraSonic Finish: the core and the sheath are bonded together at the rope ends by an ultrasonic process called UltraSonic Finish; gives greater durability and avoids frayed ends
- ClimbReady coil: specific coil makes the rope ready for use; helps the user avoid initial uncoiling mistakes and increases longevity
More effective belaying:
- diameter facilitates the use of various belay devices
- Middle Mark: indicates the middle of the rope to facilitate maneuvers
- EverFlex treatment: special thermal treatment stabilizes the core strands and improves consistency; offers excellent grip and consistent handling over time

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.
