Great lightweight harness

"Great lightweight harness for mountaineering. I will be using this a lot this summer"

Jared E. (5/5)

Light Harness

"Took this harness out of the box and straight up the mountain. Light, comfortable and functional."

Dirk N. (5/5)

Extremely tough and packable.

"The Black Diamond Couloir harness was exactly what I wanted for the Vallée Blanche—minimal, no-nonsense, and insanely lightweight. It held up through a tough, demanding day in serious terrain without ever feeling bulky or restrictive. Easy to forget you’re even wearing it, which is kind of the highest compliment for a ski-mountaineering harness."

Jeremy R. (5/5)

Light and simple

"This harness is a great light and simple harness!!"

Woodsen S. (5/5)

Fills a need

"Bought for rescue pack, never know when you might need a harness. Light weight and small volume folded up. Don't think it will fit back in the mesh bag."

Greg F. (5/5)

Nice piece of gear.

"Very light functional each to adjust."

Nikita J. (5/5)
