A versatile, go-anywhere, climb-anything rope based on the popular Eternity construction, the Mammut Crag 9.8 mm x 70 m dry rope is light enough to move fast, yet durable enough to really thrash.
- 9.8 mm size is light enough to move fast and keep your pack small, yet also durable for the rigors of climbing, so it's great for just about any climber and any route
- 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
- 70 m length allows extended leads and rappels on modern routes
- 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

Fantastic All-Around Rope
Yes , I recommend this product
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.

Couldn't ask for a better rope
Yes , I recommend this product
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.
