So light, just right

this terrifically light harness takes up less space than a couple of granola bars and weighs less. It’s the kind of thing you could toss in your pack and forget about until the moment you need it. Fits well and while it’s not meant to be super comfortable, it is exactly what it’s designed to be.

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.
