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.

need a few tweaksIn practice this sort of harness doesn't really get "used" that much... It's mostly along for the ride on ski mountaineering trips for the just in case crevasse fall or short exposed roped ridge or gully step kicking. So it's main features should be that is light, compact and EASY to put on in winter conditions. I give it good marks for being light and compact, but it is a bear to thread and double back even without gloves on. The less experienced folks I was leading couldn't manage it at all, and forget it once the harness gets damp or icy. A larger easier to manage buckle would not add that much weight or bulk and would go a long way to faster, easier and less finger numbing transitions on a tour. Until the buckle is made more winter-user friendly I would not recommend this harness.

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!

Better choices existVery light and adjustable, true. But to put on while wearing skis (one of the reasons one would buy this harness) requires threading the double-back buckle, which is barely possible with bare hands, and impossible with gloves. Furthermore, the gear loops are so small and tight to the harness as to be unusable, again especially with gloves (and this is supposed to be a harness designed for winter use!).

Not an Improvement over the last versionI was hoping that this model would be a step up from the old Couloir. As with most other reviews of this the buckle is very hard to get tight. Another issue with the harness is the point where the leg loops are sewn into the waist belt is very bulky and digs into the hip bone. This is especially apparent when wearing this harness with a backpack. This harness should be comfortable under a pack hipbelt because it seems that you would have a pack on most times you are wearing it. I would recommend fixing how the buckle threads through to ease putting it on as well as using wider and thinner webbing to attach the leg loops in order to thin down that point and make it a smooth seam.

Works OK, needs fine tuningI bought this immediately when it became available. The harness is very light, packs small and is a great companion on ski touring trips or for lighter mountaineering including shorter scrambles. The comfort is appropriate for this class of product (read "low but OK".
Two downsides, though. The main belt is terribly difficult to pull through the buckle. Safety-wise this may sound like a good thing but tying the belt is uncomfortable, messy, requires both hands and a bit of acrobatics, too. Maybe when the belt and the buckle are older this will get better.
The obvious omission is the size of the ice screws slots on the legloops. A standard Black Diamond screw - yes, your own - will not go through with the cap on, the loop is too small. Of course, when you ice climb, you remove the caps before racking up but this is no ice climbing harness, it's a touring harness. Everybody I know carries their screws WITH the caps when they ski-tour or cross glaciers and so on because you plan on NOT using the screws in the first place and there is no point in destroying your precious shells with the sharp end of the screw. How this was missed during the design phase I can't understand. Something to fix in the next generation.

Best harness for mountaineering (only)I bought this harness for mountaineering trips (only), is perfect very lightweight and good fit. For people who complain about difficulty peeing with the harness on is not true, the buckle on ether leg can be open very easy and the harness will shift almost by itself giving you the comfort for your necessities. Is correct if the buckle will be just slightly bigger this harness will be 5 stars. However since you adjust this only once on the beginning of your climbing ok may be twice I do not se such a big of a deal. I recommend this harnesses for mountaineering. The product is not designed for rock climbing or to spend significant amount of time on harness, is that's what you want go buy Petzel.

Great mountaineering harnessSuper 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.

Waist buckleThe 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.
