I’ve used this rope in all kinds of terrain so far from alpine ice climbing, long multi-pitch routes, and even cragging. My opinion is the best place for this rope is in the alpine. It flows nicely and with proper management, I had no issue linking pitches to the full rope length of 80m!

I’ve used the rope so far in a gri gri 2, DMM pivot, BD ATC guide, and the grivel master pro. Across the board, the rope flows smoothly and locks consistently with no slippage in these belay devices. Also noticed no slippage in top-down belay on vertical and traverse pitches.

I’ve mostly had this rope on ice but now that we are moving into rock season I’ve had several days on granite, basalt, limestone, and sandstone. So far the wear is minimal to non-existent. That being said with the thin diameter I wouldn’t use this rope for heavy top rope use or projecting routes. The rope also meets the UIAA standard for dry coating and on the warm wet ice days the rope hasn’t wet out at all.

The verdict

This rope is sick, I would primarily use it on fast and light multi-pitch routes, and alpine climbing. It packs down very nicely and has minimal weight. I’m stoked to get this rope out into the Cascades this summer as it will be my primary alpine cord. If you’re mainly climbing single pitch sport routes and projecting I would look into a beefier rope but this will suffice for that last minute cragging session if needed. I hope this review helps you in choosing your next cord! Send and return! Price as tested $299 on

Will Coleman

Hi, I’m Will, I’m currently living the van life in Colorado. I enjoy mountaineering, splitboarding, climbing, trail running and type 2 fun! I’m 28 years old and spend as much time outside as possible. I moved to Colorado in 2014 from Mississippi and grew up in the mid-south. I have been snowboarding since 2000 and the mountains have had my heart ever since. You can find me anywhere from riding Colorado’s high peaks to climbing desert towers, to climbing in the PNW!

Mammut Serenity Dry 8.7 Rope A Second Opinion

I love this rope! I bought it two years ago prior to a trip to the UK with my son. We were looking for the smallest and lightest rope possible to facilitate only using carryon luggage. My other criteria was that I wanted a single rope that was sufficiently small in diameter that I could use it as a half rope if joining friends. It worked beautifully in this respect. I dislike climbing with two ropes of differing diameters if I am using them equally.

Finding Grit in the Peak District

As a single rope it is light and responsive.

This makes it good for longer sports projects and especially for long multi pitch trad routes. The rope glides through belay plates when giving out rope and locks off nicely in the belay plates we use. Petzl Reverso – Wil and Edelrid Jul2 – Cai.  If I was working a sports route I would probably go for a larger diameter. It will be easier untying after multiple falls, more durable and even kinder on the belayers hands. However, if fast and light is your thing or you like big trad routes then this is the ticket.

We took it back to the UK again this year.

There are no signs of wear or abrasion. It is still its same bright fluorescent green self. The sheaf on this puppy is stronger than a bull on steroids. It needs to be with my predilection for the slaty, tottering crap that is SW sea cliffs and my tendency to use the friction from big boulders as direct belays at the top of routes.

Wil was born in North Wales and steeped in its rich maritime, mountain and river folklore. In response to the request to “get a real job” he became first a teacher then professor of adventure education.

He then emigrated to where the sun shines for 300 days and snowfalls for 100 (Colorado). During more than 25 years as an outdoor educator, he worked Scottish winter seasons, taught canoeing, climbing, kayaking, and skiing throughout the States, Europe, and Australia. He also regenerated the University of Alaska Anchorage’s Outdoor Education program. His biggest adventure (by far) is fatherhood. It has also been the inspiration for his website

Things he likes to do include (middle) aging gracefully, and skiing (telemark) aggressively. He is happiest outdoors with a good view, good company, good weather/snow and the residue of self-powered adventure; sweat, a manic grin, and wild eyes.
