Combining a small diameter and low weight, Mammut’s Revelation Dry is a great rope for winter climbing. The COATINGfinish™ on both the core and sheath ensures that the Revelation absorbs almost no water and won’t freeze at low temperatures. Mammut’s DRY ropes also boast lasting water and dirt repellancy.  In UIAA tests, DRY ropes only increased in weight by 1%.
