If you're looking for one rope to handle all your sport, trade, and top roping needs, check out Mammut's Transformer Protect Climbing Rope. At 9. 8mm, it's light enough to handle your project but tough enough for top roping, and it has a middle mark so you can always know how much rope you have to work with. Mammut made the Transformer using transfer yarn, which is high quality yarns leftover from the construction of other ropes, so it's more sustainable than most cords and has a pattern that changes every meter. It also features Mammut's Protect Coated Sheath treatment for added abrasion resistance and a longer lifespan under heavier use.
