Tie into the NOMAD for sport climbs, alpine routes, or anything in-between. Thick sheath, superior handling and a well-tuned balance between dynamic elongation and impact force make this a perfect all-around rope. Duratec Dry treatment helps prevent the rope from absorbing water which can weaken a rope and make it difficult to handle in freezing conditions. Before a Petzl rope is constructed, the core and sheath strands are individually treated, providing water repellencty in case you find yourself in a deluge, snowfield or on a dripping ice chandelier. To help facilitate descents, the middle of each Petzl cord is marked with a Black bar. Even with this marking, it's sometimes a good idea to tie a knot at the end of the rope as an additional safety measure.
