Black Diamond Chaos Reviews:


I was going to buy last year's model that was orange but this one came out just in time. I emailed a black diamond rep and he said there are 2 differences between this lime green new model and the older orange one. The yellow has hooks on the leg loops so you can drop your drawers if you need to and it is slightly stiffer with more support and burlier material in the leg loops. I have only climbed with it on about 10 climbs. At first it felt the same as my old harness and I wasn't too impressed, especially because I was comparing this expensive harness to my old mammut $35 harness. The more I climb with it the more I realize how much lighter and comfortable it is. The only complaints I have pertain to the gear loops and the speed adjust. The gear loops seem a little flimsy and when they have gear on them they tuck into your body so its hard to clip things to them. The speed adjust took some getting used to. Its speedy to get on, but its difficult to get off without a little practice. All said I love this harness and will keep it for years to come.

I had a chance to use an older version of this harness down at the Red Rock Rendezvous and loved it then, so I made sure this was my next harness. After having a chance to use the new version for awhile now, I love it. I have been climbing up at Sugar Loaf this winter where there is a mix of tr, sport, and trad climbs, and I like it for all three styles of climbing. This harness is so light weight and well padded I don't know I have it on most of the time, even while hiking. The waist belt has a great shape to it which makes for a better fit than other styles. Also, the speed adjust waist belt is nice because I don't have to worry about doubling back the harness, and in my opinion having less features is better.
The low profile gear loops took me a time or two to get use to, but I love them now because they are out of the way and not flimsy.
The one thing to thing to consider is that the legs are non adjustable. So, if you fit the dimensions I would recommend this harness

This harness looks sweet, but it doesn't fit my proportions and the sizing chart is way off. My waist measures 34 inches and my legs 25. The leg loops fit very nicely but the waist belt is way too big. I cinch it all the way down, and while it stays in place, I can move it around at will. If I put some gear on the loops it would slide right down. So much for a Large fitting waist sizes 33-36. Don't believe it. I wouldn't even try this harness in Large unless your waist is at least 35 inches. Unfortunately, I know from experience with the Ozone that my legs are too big for the medium,so I guess I'll be going for an Arcteryx R320A.
As for my rating, just based on the feel of the material and the look, this is still an outstanding harness. It's beefier than I expected, but is still light. 5 stars if it fits you.

I have the older version of this harness (Black Diamond says its only a different color, no other changes)
The harness is great and I like the fact that it is a molded shape. It fits very well and is great to belay, climb, and hang in.
I have also worn the high end Arcteryx R300 harness.
The R300 wins in comfort, but only by a bit
I prefer the Chaos gear loops, although not as big, they are better to clip
I also like the fact that the haul loop is burly and full strength on the Chaos
The Chaos wins for me, because it cost me less money, but if I were doing more alpine routes or long approaches I would have kept the R300

I first got the Chaos in a medium as I'm a 33 inch waist. It was really snug and the leg loops were crazy tight. So, I moved up to the large and the legs are still a bit snug but the waist is perfect. Moving from an old BD momentum harness I miss the adjustable leg loops but otherwise find this harness much more comfortable, lighter and equally utilitarian. The full strength haul loop in back was essential for me and this was the BD option that carried that feature without being an ice-specific harness. So far I've climbed on it about 7 days and I'm loving it.

the ONLY reason that I didn't give this harness a 5-star review is the non-adjustable leg loops. if I were using this strictly for the summer or indoors then this would have worked out great. the harness is ridiculously comfortable. the non-adjustable leg loops just weren't going to cut it for me though as i wanted to be able to maybe wear some warmer clothing at times. i ended up going with the BD Aspect instead. I'm about a 33 in waist and the waist sizing on the medium was just great. fully recommend this harness if you're not going to need to worry about the adjustable leg loops.

Got this harness as a replacement for my incredibly old Petzl. Man am I glad I made the switch! I hadn't realized how light harnesses have gotten over the years. This feels like there is almost nothing there. It is incredibly comfortable too while sitting in it for a while too. No pain or numbness at all. The non-adjustable leg loops are different but not that bad. They just take a time or two to get used to.
Overall definitely a great buy and I would recommend this to anyone!

Thomas Briley at on 05/01/2012

I had this harness for a couple days and the fit seems to be off for my body type. I am tall and skinny 6'2". The thing to make sure with this harness is that the leg loops aren't adjustable. My legs happened to be little to skinny to make this a comfortable harness.
I'd recommend if you have the cash and want a really light weight harness, but double check your leg loop sizings.

I use Arc's 300 for backcountry and ice climbing but this is without a doubt the most comfortable harness I have ever owned. I have hung in it for extremely extended periods of time and hauled good loads on the gear loops and this harness has never let me down or disappointed me in any way.

Used to have the Black Diamond Momentum SA and this is by far the most comfortable harness I have ever stepped into. 100x more comfortable than the Momentum and Focus.\ Great harness
Recommended to anyone that is tired of their waist and thighs hurting all day.
