With next-generation technology for performance rock climbers, the Mammut Crag Sender 9.0mm x 70m dry rope provides high levels of durability with exceptionally light weight.


  • Sender construction optimizes durability and handling
  • 70m length allows extended leads and rappels on modern routes
  • 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
  • Triple-certified for use as a single, half or twin rope
  • bluesign® approved product means the company took deliberate steps to reduce negative impacts on the health of the environment, workers and users


Note: Half and twin ropes are designed to be used in matching pairs (size, length and brand should match). Using a mismatched pair can cause excessive wear on the ropes, exposing you to a higher risk of rope failure. Never climb with only 1 half or twin rope, unless it has also been rated as a single rope.
