The Cosmic is a one-size-fits-all harness that features the same geometry as our regular harnesses. You put it on and use the belay/rappel loop in the same manner as you would on our Eldo or Diamond Harnesses, so there’s no need to learn a different system when you change harnesses. Great for ski mountaineering, glacier travel, clubs, gyms, rental programs or just to have around when a friend drops in.
