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.

  • Features

    • 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
