Why We Like The Couloir Harness

Best Mountaineering Harness Around

This incredibly strong harness is extremely lightweight and minimalist without any sacrifices to comfort. There is plenty of gear attachment points for clippers and ice screws. This harness is very easy to put on and take off and feels very secure while climbing. I highly highly recommend this harness

Light weight!

Much lighter than what I was using. Fit pretty well, but was a slight struggle loosening and tightening the belt strap.

Light weight and easily packable

Purchased this for a mountaineering trip coming up, I can already tell this will be the go to for many adventures. It is easy to get on and off with with all my layers; seems to have the right amount of loops and feels light and comfortable. I give it 4 stars because I need a little more time with it in action.

Ultralight

I purchased this for a Rainier climb and other ski mountaineering objectives. This is replacing my old Momentum harness due to its low weight and simple put-on and non-step-through features.

Perfect for ski mountaineering or glacier travel. Takes up almost no space in the pack & dries fast.
