    Great harness

    • Familiarity: I've used it once or twice and have initial impressions

    I have used it for a few climbs, with a couple rappels involved. It is super lightweight, you don't notice it in the pack, and you don't notice it hiking either. I hiked out with it on because it was so comfortable. The buckle is a bit hard to fasten and double back, very hard with gloves on. You don't want to hang in it much though.

    Mountaineering Essential

    • Familiarity: I've put it through the wringer

    It weighs nothing, packs down to the size of a soda can and is barely noticeable when you're wearing. Nothing more need be said. In the mountains it'll do it's job perfectly, at the crag not so much. If you're looking for a great harness for any type of mountaineering or glacier travel this is on the short list

    A Backcountry Nececcity

      If you are out ski or splitboard touring, hiking in remote locations or any spot you are excited about the adrenaline aspect you should have this in your pack. It takes up less space than your water or first aid and can get you to places that are inaccessable to those without. This is your credit card in the backcountry.

      Light and Functional

      • Familiarity: I've used it several times

      Even knowing that this is a lightweight, minimalist harness designed for maximum pack-ability, I was shocked at just how small it packs down. It packs down to about the size of a can of beans and weighs considerably less than one.

      I bought this for occasional short ski mountaineering rappels and it works great for this purpose. You can put it on over your pants without taking your skis or crampons off. It's obviously not as comfortable as a padded climbing harness, but it's fine when you're just hanging in it for a few minutes.

      Pair this with a short 30 or 40 meter 8mm rope and some basic anchor building supplies and you've got a "just-in-case" rappel kit that only weighs a few pounds. Perfect for skiing obscure seldom-skied couloirs and lines that might sorta kinda go through.

      Size matters

      • Familiarity: I've used it several times

      This is the smallest harness I have come across and for that reason alone it is the best choice for ski mountaineering. People love to wax on about how you shouldn't take a lead fall on it or it doesn't have such and such a feature but again we are just using this for rappels, it just needs to be small and light and it is. It isn't special in anyway except it takes up no room whatsoever in your pack and weighs nothing and that's all I really care about in a harness.

      You forget you have it sometimes...

      • Familiarity: I've put it through the wringer

      I've had this little guy for quite awhile now - such a versatile harness. Whether for the so so person you are taking climbing for the first time, the ski tour that is going to turn into that awkward rappel if you didn't have it in your pack, or the once in a lifetime heli trip deep in the Chugach mountains of Alaska where everyone watches on the movies and then drools over it year after year. As a harness, it is super functional. I definitely would not use this at the gym or at the local crag, but then again you don't take a knife to a gun fight. You would however, take a gun to a knife fight, but that is a different topic. The gear loops are flexible which help it compress down into the teeny tiny pouch that it comes with. You could throw it in your touring pack and forget that you even have it until after that weird Munter hitch rappel off your backpack waist belt that scared you into wondering why you didn't pack the harness... The haul loop is great for pulling the sled behind you as well. Just don't forget to double back the waist belt tail - it's not the same buckle as on their other harnesses!

      I am 5'8", 170lb with a 32" waist. I have the small/medium harness and it fits well over plenty of layers, or is just right with minimal layers on the high output spring days.

      You forget you have it sometimes...

      Perfect for 'maybe need it' trips

      • Familiarity: I've used it once or twice and have initial impressions

      If I'm not sure that I will need to be hanging off a rope (glacial mountaineering, exploring crags with a slight chance of needing to rope up, or knowing that I will need a harness just for one pitch), this harness is perfect. Bare bones, very light, not super comfortable, but the lack of padding is where you get the weight savings. Packs so small, I'm more apt to bring it along as a 'just in case' item. Love it!

      Light and reliable

      • Familiarity: I've used it once or twice and have initial impressions

      I have not used this out on the mountain, but have practiced rope work, prusiking and crevasse rescue drills with it and it seems great. The harness feels surprisingly comfortable while still proving light and packable. Even while hanging in the stripped-down harness for prusiking up a rope, it seemed well-balanced and supportive. It folds into bag about the size of a pop can. As far as the buckle, it takes a little extra dexterity, but it was not nearly as much of an issue as I feared after reading other reviews. Once it's on, it's easy to forget about. Overall, I think it should work about as well as anything for mountaineering needs.

      Light, Packable, Trustworthy

      • Familiarity: I've put it through the wringer

      I love this harness and I think every ski mountaineer will too. It's light, durable and you can trust that it works for a variety of different purposes. Whether your rappelling or need to be roped up on a glacier or while making a ridge traverse with a bit of protection, this harness is for you. The mountaineer, the traveler, the weight conscious. The only reason I'm not giving it a 5 star review is because I think the sizing is a bit weird. I recommend for anyone using this with ski gear over over more than one layer of clothing to buy the size large. I have a small waist and this harness in size M barely works with my ski pants.

      Light, Packable, Trustworthy

      Great for mountaineering

      • Familiarity: I've put it through the wringer

      This is a mountaineering-specific harness - don't buy it expecting lots of nice padding for long hanging.

      It's great as a super compact, lightweight harness for mountaineering, skiing, or glacier travel. For any kind of trad climbing I would look elsewhere. I love it for the climbing gym as it packs down smaller than a Nalgene (and typically you're not hanging for very long in the gym). During two long rappels in RMNP (Colorado) this harness became quite uncomfortable with its lack of padding. Only 2 gear loops which makes racking a lot of gear during an alpine climb a bit of a hassle. The double-back buckle is also a hassle and the small diameter webbing is tough to adjust with heavy gloves on. The adjustable/unclippable leg loops allow you put this harness on over mountaineering boots and crampons easily (skis as well I imagine).

      As long as you understand what you're getting into, this is a great harness. I bought a Petzl Aquila for sport/trad/long alpine routes and keep this one as a backup. Just my $0.02.

      Initial Impressions

      • Familiarity: I've used it once or twice and have initial impressions

      Tried it on and thought to myself "this is a pile of junk, how is it going to hold my weight?" Well I tied a rope onto my stair bannisters and hung from it to test it before I went on a mountain. The Harness is super duper light, extremely durable and strong, can pack down just like a down jacket and most importantly, its comfortable.

      Small size, Big punch.

      • Familiarity: I've put it through the wringer

      For skiing in glaciated terrain, ski mountaineering or just even the quick ski cut, this is the best harness there is. So dang light and extremely packable making it easy to throw in your pack for when you don't need it and quick and comfortable to put on when you do. Skiing's best harness.

      Strap up for that summit

        Obiously light and geared toward mountaineering, so don't let that cheap price tag sway you. That said, you can put on over my skis (god send)! Only hitch is the sizing, make sure to go bigger than you think, you'll most likely be wearing more layers than you think. Better to have a harness that fits at the summit than the approach trail yea?

        Strap up for that summit


          This harness is very basic and light. Not ideal for very long rappel, because your tapes may not have much comfort. But it is great for those who want to make tracks in which there are obstacles that require climbing or descending. I liked!


          • Familiarity: I've put it through the wringer

          Have used this harness for a bit of everything, mostly glacier travel but also ice climbing and rock climbing in a pitch.


          - tiny, lightweight. This is a very big pro, as it weighs almost nothing and packs enormously tiny. Note: not very padded, so I use a different harness if I plan to hang in it at all.


          - the front buckle is the worst buckle design in the history of buckles. It's really hard to double back in a warm room with bare fingers, and almost impossible to do when you are very cold with gloves. There is no earthly reason it needs to be so difficult.

          - the little buckles holding the leg straps up (well, it appears that is their intended purpose, I don't see them actually doing much) have broken and now dangle forelornly. I would have to have them re-stitched in order to replace them with a different buckle. So I tie the little straps to something so they don't get caught. They are not weight-bearing but the buckle is still poor quality.

          All in all it's decent, it's light and small and there are many occasions where that is the most important, but it could be made with better buckles and save us all a headache. You may want to consider other alpine harnesses.

          I would have to absolutely agree with the buckle design. Although I use this harness exclusively on cold trips where I am providing the padding with extra clothing, getting the front buckle going at 10 degrees during a pitch black alpine start is horrendous.

          Although it seems it is not the intended use, can this be harness be used for lead climbing on sport routes?

          In a pinch yes. But it would be uncomfortable. The fabric gear loops are tricky to unclip wire gate biners from.

          You'd have to tie into a locking biner off the belay loop.

          If you're trying to have one harness for Alpine and sport, This is not it.

          The BD Bod would be a better choice in terms of comfort and functionality of the harness.

          Trust me... NO ONE wants to take any kind of lead fall in a webbing harness with no padding.

          Am looking at the comparison between the CAMP USA Alp 95 harness and the BD Couloir. First question is how small does the BD pack down to and is it worth the extra weight to have a slightly more adjustable leg loop?

          * main use for rap and accasional tricky bits and looking for ultra light (not comfort) since I have a good climbing harness for any bigger objetives

          Would any of you folks that have purchased mind sharing your stats,the size you got, and the result. Im 6'2" 205 lbs with a 34 in waist. Thinking Im M/L here but its tough when Im usually on the larger end of things.

          Best Answer

          I don't own this, but I'd recommend the the L/XL if you're using this for alpine ventures. My reasoning is because you'll have layers, and it's better to be safe than sorry. This harness is super adjustable, so I think it should suit your needs. Best of luck!

          If you were to decide between this harness,...

          If you were to decide between this harness, and the Arc'Teryx S220 for light alpine situations, which would YOU choose?

          Best Answer

          You're making a tough comparison, as the two harnesses are not in the same "weight class" The Arc'Treyx S220 has padding and much more robust leg and gear loops than this harness. It's like comparing a Yugo to Lincoln Town Car.

          You'd do better comparing the Arc'teryx S220 to the BD Momentum AL. In that case, I'd say get the BD Momentum AL.

          Really? It seems like they are in the same class to me. First of all, there is only 10g difference between the two. Second - both are marketed as packing incredibly light/ small. Third - both are to be used for alpine climbs when you won't be sitting in the harness for long. Sounds like a lot of similarities, other than the leg loops...

          As far as glacier travel and other non-technical climbing scenarios, the Couloir is superior to the 220. They're not really in the same 'class' because the 220 is pretty much a normal harness whereas the Couloir is a lightweight harness primarily intended for situational use in the cold, when you are wearing a bunch of layers.

          Would this harness work well for glacier...

          Would this harness work well for glacier travel and some low class 5 climbing, not really expecting to fall on the climbing but not confident enough to solo it. The reason steering me toward this harness is its packability and weight, also like the ice-clipper slots

          Can this harness actually take vertical...

          Can this harness actually take vertical falls? Ie, would it be a bad choice for regular climbing?

          Hey Evan,

          yes it would be a very bad choice for "regular climbing" since it's designed for (winter) mountaneering.
          The harness only consists of (strong) webbing to make it light and small therefore the usual padding (to make falls reasonably comfortable) needs to be provided in another way. In the harness' designated application this would be by wearing several layers of (winter) clothes underneath.

          To answer the first part of your question: yes it will "take vertical falls" BUT it WILL hurt if you're only wearing shorts!

          So for regular climbing I'd pick a different one;)
