- Dry treatment meets the UIAA standard for water repellency, absorbing just 1.5% of its weight in water even after surface abrasion, making the rope more durable
- Special heat treatments incorporated into the dry process increase the tenacity of the nylon fibers, making the rope much more abrasion resistant than a non-treated rope

- Ready-to-climb packaging improves handling of the rope
- bluesign® approved product means the company took deliberate steps to reduce negative impacts on the health of the environment, workers and users

Excellent Rope
I got this as my first rope, and I must say it was the correct decision. I have used it on all my climbing adventures, and I haven't noticed any damage through numerous falls. It's been rubbed up against rocks and has maintained the integrity of it's sheath. It's a rope I found just works with belay devices, and doesn't have any of the annoying characteristics of some ropes; it doesn't slide through or require excessive weight to let slack out.
Bright and durable
This rope is great!! The dry treatment makes it more durable than previous ropes that I've had. It has held up to some pretty gnarly rope drag over the last couple of months while showing very minimal signs of wear. Dust and dirt don't stick to it either, so even after a few months of continual outdoor use, it's almost as bright as it was when I first pulled it out of the box. Due to the dry treatment, the feel through a GRIGRI is pretty slick at first but it got better after a few uses. The rope is very dynamic and the catches are softer than I've felt with any other rope. I can see this rope standing up to many different uses!
Decent but the middle mark fades quick
I like this rope and I don't mind the stiffness that others have talked about with being a dry rope, but I am disappointed that the middle marker is wearing off so easily. I have used this rope exclusively for ice climbing and after about 8 days out the middle marker is getting hard to see on the bright orange rope. I got the bright colour because I thought it would keep the middle marker visible. I'm not sure if there's a product to use on the rope to darken the middle mark or not. I have had a few sections freeze as well, time will tell if this is an issue. If you don't care about a middle mark then this is a solid rope.
Fantastic All-Around Rope
Very impressed with this rope. While not the thinnest rope for hard sends, it’s a good middle ground between weight and durability. Been used on everything from projecting hard stuff, top-roping with kids, shorter multi-pitch excursions, and week long sport climbing trips with overall minimal abrasion and fuzziness on the sheath. If you’re looking to buy one “do-everything” rope this might be the one for you.
How long will my rope last
It’s 2024 my rope was made three years ago Is this safe I could of bought one for 100 off local 3 years old never used
Manque de durabilité
Plusieurs sorties d'accumulées avec cette cordes, vraiment content ai début. Feed super bien, légère pour le diamètre et on ne peux pas la perdre de vue! Malheureusement, après une demi-saison de grimpe (environ 25 jours de grimpe) la corde est très usée, elle n'est clairement plus "dry" et s'effiloche beaucoup...elle n'a pas prit de chute, mais elle montre des faiblesses à plusieurs endroits et j'ai décidé de la mettre de côté pour retourner à ma vieille corde qui a plus de 3 ans et est en meilleur état. Dommage, j'adore les produits mammut en général.
As others have said, this rope is really stiff. I'm hoping it will get better with time, because it has not been enjoyable for me to use at all. It's difficult to flake and is very frustrating to feed slack through a grigri. It's also hard to tie a tight figure 8 - in fact, the second climb I did with this rope, my knot partially untied. We always do partner checks, and I'm 100% certain it was tied correctly when I started the route. I had at least 8 inches of tail and pretensioned the knot as much as I could when I tied it. I noticed this as I was pulling the crux and had to downclimb to a ledge to fix it. This could have ended much differently had I not noticed. On the plus side, it seems durable I guess?
Some of the reviews on this mention the rope being stiff and slipping out of knots, and I could see how that might happen, but it also seems to have undergone a redesign from past versions. This rope definitely is slick on the sheath, but this seems to only make the rope easy to feed through a belay, and I haven't experienced any knots slipping, even with short tails. The dry coating is definitely effective at repelling dirt and preventing damage through repeated uses. This rope has been solid since out of the box, and whips on it have felt clean.
Couldn't ask for a better rope
Wow, this rope was so awesome. I got to take it out for the first time the other day with buddies and I really thought that it checked all the boxes. Just opened the packaged and was climbing ready. The rope was smooth and easy to handle while on belay. It was a nice weight and not to bulky when lead climbing. I highly suggest the rope to anybody looking for the one rope to do it all.
I've been using this rope every weekend for the past 2-3 months outdoors and it's still in good shape and safe. I took a couple big falls on it and it performed as expected. It felt a little sticky on the Grigri on the first day, but that was it. After two or three climbs it became smooth. The only reason I'm giving it four stars is because the middle mark is not too clear now, after using it several times. I'm not sure if it's because it washed out a bit or maybe the rope is just too dirty (probably a bit of both).
