Black Diamond Couloir Harness

- +

Ideal for ski mountaineering adventures.

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.

Perfect for Rainier's standard climbing routes, the Couloir has minimal padding on the waist and legs to allow for comfortable glacier travel.

Plus, two 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 corselettes, extra biners, and other essential gear.

Why is this a Guide Pick?

Kiira Antenucci

The BD Couloir is the best alpine harness. It is fully adjustable while also being minimal, great for warm weather climbs when you layer down, and great for cold weather climbs when you have all your layers on.
