Petzl Fuse dry rope features a stout sheath for durability on sport climbs and a small diameter to keep the weight light and handling easy. Smaller 9.4mm diameter lowers overall weight while providing improved handling characteristics. DuraTec dry treatment not only repels moisture, but improves durability by increasing abrasion resistance in both the sheath and core. Dry treatment helps preserve the outer sheath by reducing fuzzing of the sheath fibers while the inner core fibers benefit from lower overall friction. Crag-ready coil allows the rope to be used right out of the package butterfly coil prevents tangles and kinking, just tie-in and start climbing. Safety markings at the midpoint and at 6 meters from each end of the rope help prevent lowering and rappelling accidents. Kernmantle design combines a durable braided sheath with a shock-absorbing core for protection from fall forces. Meets or exceeds UIAA tests for falls, impact force and elongation. 70-meter length works great on longer leads and rappels.
