Mammut 10.2 Gravity Dry Rope. Extremely robust single rope with high safety margins! With a diameter of 10.2 mm, the 10.2 Gravity Dry offers a high fall rating and great durability. New for Spring 2015 Mammut has reinvented their dry treatment process, as the UIAA has rolled out specific dry rope testing standards for the first time. The Gravity Dry rope has a coated core and sheath thanks to Mammut's patented COATINGfinish technology which creates lasting water and dirt repellency. It held onto only 1% of its weight in UIAA water repellency test making it an excellent choice for winter climbs or wet sport and trad single pitch conditions. Whether you are guiding clients, running outing club trips, or just taking your climbing from the gym to the crag the 10.2 Gravity Dry offers lasting security for years to come.
