Sterling Duetto 8.4 mm XEROS is a high-level half rope for climbing, also certified as a twin rope! Super versatile, it allows you to perform at your best on long traditional and sport routes, as well as on ice climbing.
Thanks to the diameter of 8.4 mm and its dynamic characteristics, it is the best you can wish for when facing significant and challenging run outs! Reliable and durable, it also has an exceptional feel. Smooth and slick, it makes clipping easier and allows for better and more precise belaying.
Its qualities do not end there! The XEROS technology, exclusive to Sterling, takes the concept of Dry rope to another level. Unlike other treatments that make only the outer sheath waterproof, Sterling has developed an innovative manufacturing process that treats every single fiber that makes up the rope, from the core to the outer sheath. This concretely translates into safer and more performing ropes in humid conditions, allowing you the freedom to focus on climbing without worrying about your safety.
