"The only speed harness I use in training and competitions. My first Couloir lasted 3+ three years through 15hr/week training and endless comps. This is my second and it will be well used."
"Lightweight fits very comfortably and is very adjustable, its a lovely harness!"
"I updated my harness after 15 or 20 years. I am impressed with the improvements you've made. The new one is lighter and the main buckle is considerably easier thread. Thumbs-up!"
"Extremely lightweight and surprisingly sturdy with proper care. I haven’t tested it in alpine conditions yet, but it performed very well for sport and competition climbing despite not being designed for that use. I'm extremely excited to put it to use in the mountains."
"Use this for mountain rescue ski pack like its ease on with gear"
"Lightweight and effective for mountaineering"
"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."
"I love the weight and comfort of this harness. The clips on the leg straps allow me to take it on and off easily."
"Perfect for the mountain"
"Light as they come, just make sure you know what you’re getting."
