The Black Diamond Couloir Harness features a minimal design that's low-profile and keen on weight savings. It's incredibly lightweight for a technical climbing harness and compresses down smaller than the size of a Nalgene. The padded leg loops distribute weight evenly to reduce any pressure points, and the fabric is quick-drying to keep you comfortable for the duration of your climb. A rear drop seat and front buckles make for easy on and off, especially while wearing crampons or chunky ski boots.

FEATURES of the Black Diamond Couloir Harness

  • Redesigned ultra light construction with hydrophobic fabric and Fusion comfort technology
  • Speed buckle for easy on/off while wearing skis or crampons
  • Two webbing gear loops
  • Four ice clipper slots with ice screw slot in each leg loop to reduce clanking
  • Full-strength belay loop
  • Extremely light, packable and low profile
  • Primary fabric is bluesign approved

Rated 5 out of 5 by from Good, compact, and easy to move with I keep this harness buried in my pack to use for winter response for search and rescue. It’s lite weight, holds 6-10 biners and doesn’t impede movement at all. This is not designed to be comfortable while hanging in it, but when needed, it’s there.

Rated 5 out of 5 by from Great mountaineering harness Super light, compact and still has some padding. I've read a lot of complaints about the buckle being small- I don't have a problem with it. It's a speed buckle, which is nice (no double-back), and I like the fact that it has a lower profile than a "normal" climbing harness buckle. Everything sucks with gloves on, but I don't expect to be adjusting this that often. Belay loop construction is better than older Bod-style tie-in (I think at least) and the ice screw slots along with gear loops are a nice touch.

Rated 3 out of 5 by from Functional not easy to put on. Small and light weight as they should be for mountaineering. I struggle with how hard it is to tighten the waist strap. I would have bought something else had I realized how difficult the strap would be.

Rated 3 out of 5 by from Built for Speed not Comfort...& BAD waist buckle! Got this harness for ski-mo, and it does everything I need it to. It's incredibly light and does compact down small enough to fit into a jacket pocket. That being said, you would NOT want to spend any time hanging in it as it feels like a tourniquet is being applied to your upper legs after anything more than a short rappel. Also, as many users have said, the waist buckle absolutely SUCKS! BD, you guys have to do something about this. It's hard to put on, hard to take off, hard to adjust, and really takes away from the overall quality. I could tell as soon as I tried it out in the shop without gloves that this would be a problem. I needed an ultralight harness so I got this one anyway, but that obnoxious buckle almost makes the whole thing not worth having!

Rated 5 out of 5 by from don't know why people can't use the buckle i was worried about the buckle but upon getting it out of the box it was super easy to take apart and put back on. packs down small and will be a great addition to my emergency repel pack.

Rated 1 out of 5 by from Waist buckle The worst waist buckle design I ever seen on climbing harness, even ancient old BD Alpine Bod had easier one to operate. Otherwise neat and pretty construction belt and leg loops, buckle was a deal breaker for me.

Rated 4 out of 5 by from light, strong, overall a good lightweight harness I also bought a Petzl Altitute, whose similar product design and purpose with BD Couloir. Compare with Petzl, BD Couloir's belay loop looks more stronger. It is simple, easy to pack and light (but more weight than Petzl Altitude) There is only XS size for BD Couloir and that's why I bought it. Overall it is a nice harness, but I don't like the elastic cords on the back of leg area.
