Mountaineering harness -
The Couloir Ultra Blue/Black is a mountaineering harness from the brand Black Diamond.
Simple and lightweight, allowing you to make good progress on high-altitude hikes, the Couloir is equally at home on ski touring, on glacial terrain or on technical high-mountain routes.
The harness is made from a Dynex single-strandstrap. This makes it lightweight and compressible whilst maximising durability. Furthermore, the technology Infinity loop used in the trigger guard makes it seamless, durable and impossible to flip.
In terms of ergonomics, there is a waist adjustment buckle and two straps that make it easy to put the harness on, even whilst still wearing your skis. At the waist there are two gear holders and four loops for ice screws Ice Clipper; two buckles on the thighs also allow ice screws to be attached.
To all mountaineering and ski touring enthusiasts, the Couloir is the harness to ensure your safety in the mountains.
