A compact, soft and very light rope with a diameter of 9.7 mm has a certification for the single rope version. A pioneer of the first thin ropes, the Booster offers excellent strength. Thanks to coating options, the rope is suitable for all outdoor uses but because of its thickness it is best suited for very experienced climbers. The Booster comes with the Dry Cover coating. All the Booster versions are equipped with the UNICOREĀ® technology that prolongs the life of the rope by connecting the core and the sheath.
