Petzl focused on keeping its Paso Dry Climbing Rope as light as possible to keep the weight off whether you're climbing ice, mixed, or mountaineering. Its 7. 7 millimeter diameter makes this an excellent rope for very technical climbs across glaciers, through thin crevices, and up steep precipices. Petzl treated this rope with Duratec Dry to resist water, dirt, and abrasion as well as to enhance grip and handling in cold, wet conditions. The EverFlex treatment stabilizes the core's strands to help even more with consistent handling, and an UltraSonic finish bonds the core to the sheathe to eliminate frayed ends and increase this rope's overall durability. The ClimbReady Coil lets you uncoil this rope out of its package without tangles. So, go climbing already.
