Black Diamond 3S Couloir Harness

Designed for climbers and ski mountaineers who value simplicity and reliability, the Black Diamond Couloir 3S is a lightweight, unisex harness built for fast and efficient use in alpine environments. Its high-tenacity polyester webbing offers durable support, while three metal speed buckles make it quick to put on or take off—even over skis or crampons. A reinforced tie-in point, two gear loops, and ice clipper slots give you all the racking options you need for your next glacier crossing, ski tour, or winter climbing objective.
