Adding to cart… The item has been added


For technical big mountain lines, crevassed ski terrain or moderate glacier climbs, the Black Diamond Couloir Harness is a full-featured technical harness that packs down to the size of an orange and easily stashes in your pack or jacket pocket. Redesigned with a breathable, low-profile vari-width Dynex monofilament webbing that’s ultralight and durable, the Couloir comes with one speed buckle on the waist with easy-adjust wings and diaper-style leg loops that make for easy on and off while wearing skis or crampons.

The Couloir also includes BD's patented Infinity Loop for belaying, which is durable, low profile, and eliminates the dreaded belay-loop shift when the belay loop seam catches. Four Ice Clipper slots pair with an integrated ice screw slot in each leg loop to reduce clanking during long approaches and flat glacier travel, and two webbing gear loops secure cordelettes, extra carabiners and other essential gear.
