A versatile, go-anywhere, climb-anything rope based on the popular Eternity construction, the Mammut Crag 9.8mm x 70m dry rope is light enough to move fast, yet durable enough to really thrash.


  • 9.8mm 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
  • 70m 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
