Alpinist Gear Review rating 4/5

Though it's true that the Serenity is applicable for all types of climbing, I still consider it a specialty cord. (Mammut states the Serenity is ideal for sport climbing, alpine climbing, comp climbing, mixed and ice climbing and multipitch climbing.) I wouldn't want to fall on it, on lead or when following, on Eldo's rough, sharp sandstone. The thought of the slinky line rolling over sharp edges and through loose rock gives me an uneasy feeling. For hard adventure climbing on loose terrain, I'll stick to a thicker cord every time, even if just for the piece of mind.

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.
