The Beal Ice Line Dry Rope is a lightweight half rope that excels at ice climbing and mountaineering. Used in pairs, the half rope system is great for alpine and ice climbing. Buy in pairs with one light and one dark rope so you can tell them apart. This system allows the leader to alternate which rope is clipped into each piece of protection to reduce rope drag on routes that wander and zig-zag. It is also beneficial when climbing in sharp edged areas or when you need a second rope for long rappels.
