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.

So there is lots to think about and the Serenity would never be my choice for climbing on rough gritstone or certain other high friction rock types. I also wouldn't bother choosing it when a short walk in means I don't need the pack ability or weight saving they offer. However, when faced with a heavy pack, a full on mountain day or a long walk in, the Serenity is worth every penny and the Serenity is currently my first choice for both personal and professional use on long multi-pitch and mountain routes. I have also found the Serenity lasts well if managed carefully and the rope is a dream to handle providing the thin diameter is factored in. Well done to Mammut for producing another innovative and high quality product. So, if your budget allows and the rope suits your requirements, I would really give the Mammut Serenity a close look. You won't be disappointed.

Performance: We refer to ropes as “buttery” when they’re lightweight, supple, and easy to clip, and the Serenity embodied this. One guide tester chose this cord over his 12 others time and time again. It’s the thinnest and lightest (51 g/m, so 6.8 lbs. for 60 meters) single rope that our testers have climbed on; they used it at crags like American Fork, Utah, and alpine-heaven Mt. Whitney in California, where they praised it for not adding considerable weight to already-overloaded packs. One tester was hesitant about the diameter at first, but he quickly gained confidence after watching the rope rake over granite, sandstone, and rough limestone with no signs of wear or fuzz. Mammut’s Coating finish protected from abrasion, moisture, and dirt, which is the true rope killer.
Drawback: It’s not technically approved for use in some belay devices, including the Petzl Grigri 2 (designed only for ropes from 8.9 to 11mm), but testers found that the Grigri 2 still bit down on the cord, with no slippage during belaying, taking, or falling. Still, the belayer should be attentive at all times. Bonus: This rope is certified as a half and twin rope, too.

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.
