7.7mm Evolution Ice Thong 70m 2xDry



no ratings


The Ice Thong is a 7.7mm twin rope that is both lightweight and compact, a major benefit when you want to share the load on that long approach hike.

Evolution series are the original ropes that Sterling offered and are engineered for an ideal balance of diameter to weight.

Alpinist Gear Review rating 5/5

Sterling twists the sheath yarn in production, making this baby last longer. The rope is also versatile: the manufacturer claims the Ice Thong is a good choice for ski mountaineering, alpine/mixed, mountain/expedition and ice climbing. I will definitely carry the 7.7mm Ice Thong in my pack in the future.
