For the price I was expecting a decent mid range harness that fit comfortably, had good wide pads and would tighten up to look roughly like the picture (maybe with an extra inch of strap).However, this harness does not meet those qualities. I ordered a large (I'm a 33 inch waist) and the harness requires a large amount of the strap to be loosened to fit. This means that if you keep the clip loop in the centre then the thigh strap attachment at the back is shifted off centre at the back, pulling uncomfortably on one leg. Additionally there is a decent portion of uncomfortable strap sitting on you, rather than slightly more comfortable padding.This brings me to the padding, the waist pads are thinner than I was excepting and the rigid (and few) equipment loops ... MoreFor the price I was expecting a decent mid range harness that fit comfortably, had good wide pads and would tighten up to look roughly like the picture (maybe with an extra inch of strap).However, this harness does not meet those qualities.

Overall you are constantly aware of the harness sitting on you uncomfortably and for longer sessions this can be maddening.Lastly, the thigh straps on this struggle to fit well (anyone who exercises regularly and has even slightly developed thighs will find this) and the padding is oddly shaped so that it never quite feels right at any position.I'm sure, being black diamond, that the material is good and it's well made etc. But beyond that, this harness doesn't shine. If you want something more fitting and comfortable for the same price either choose a larger size or go for a less premium brand.

During hikes and backpacking trips we always end up climbing something, bouldering and rappelling something. I typically take my mountaineering harness (Petzl Altitude). It is so compact and light. It fits everywhere. But I wanted something still on the light side but more on the comfortable side. Don't get me wrong, the petzl altitude is awesome for mountaineering. But when you are climbing or anything in the middle of summer and have to hang with it for a while, it gets uncomfortable. So I ended up getting this one. It is a little more bulky than I wanted it to be but works. It is comfortable. It is a good beginner, entry level or climbing on a budget. I will recommend it more as an indoor, GYM sport climbing type of harness. Depending on how small or big it fits ... MoreDuring hikes and backpacking trips we always end up climbing something, bouldering and rappelling something.

The gear loops are asymmetric and sometimes it feels awkward on lead trad climbs. Due to that asymmetry it does not get a 5 stars from me. But I will definitely recommend it as an entry level.

It's pretty commonly accepted that the BD Momentum ought to be your first harness; either it or the Petzl Corax. I used both and found this one a little more comfortable in the legs when hanging, FWIW. The ONLY reason I dinged it one star is because of the single waist buckle; which, if you are at the cusp of a size range, can cause the belay loop to be off-center. If you ARE at a cusp, I strongly recommend you consider the Momentum 4S, with two waist buckles, assuring your ability to center the belay loop. Either one represents excellent value and will provide you with comfort and performance, indoors and out.

Good little beginner harness. Lightweight. Compact. Good padding. Spent a whole day climbing/rapelling in it with comfort. I chose the wrong size, it works, but I should have gone up a size for a better fit. I still loved it.Currently wear mens pant size 32, purchased harness size M and probably should have purchased Lg...by the time you figure extra space for clothes.Wearing skin tight leggings/climbing pants, the Md was fine. Wearing search and rescue cargo pants was a little rough. So consider your clothing and if you are on the border of the fit, maybe go up a size since there is often overlap in the size ranges with the adjustability of the harness.
I tried to buy a Petzl but their largest women's size was too small in the thighs. And I'm not a giant by any means 🙄. I was very happy to find that this harness did fit me and is comfortable and cute as well! I think it could be more comfortable for belaying but I only do it for about an hour at a time so it's not the most important feature to me.I have used this harness a few times a month for th past 6 month indoor climbing only.Perfect for beginners for indoor climbing. Easy on and off. Fita bigger than Petzl.
Great kit, good quality materials.The carabiner is top notch, it's sturdy and reliable.Same can be said about the harness and the ATC.Chalk is very finely grained, almost like a facial powder. I've learned that I prefer chunkier chalk, but this is just a matter of taste.The only drawback is that you get a random color chalk bag and I got mine in black. I wanted something brighter so I exchanged it with my friend.
I bought my first Momentum harness 20 years ago, as a teenager just starting out. While even though it’s a “beginner” harness, there’s nothing about it that says low quality. The thing served me well even after I was no longer a beginner. I used it heavily for sport climbing, canyoneering, ice, you name it. I sent it through the wringer and only retired it because you’re supposed to retire these things after 7 years just to be safe. I then upgraded to a more expensive model but now that I have kids, guess what the first harness I went to for them? The Momentum! Even though it’s a beginner harness, it works amazing and will serve the wearer well even after “moving up” in skill level.
Based on the sizing specs, I tried this in a Medium, but I could not fully tighten up the waist and legs (kinda loose; not 'safe' snug). So I returned and picked up a Small. Strangely, on the Small I must open the waist strap as wide as it goes and even then I can just barely barely barely get it on over my (not particularly large) hips/butt with some aggressive wiggling and writhing, after which the remaining tag end of the waist strap is so snugged up to the buckle it's difficult to get enough finger purchase to back-strap for a proper fit. Can I make it work? Yeah, with some effort. But I'd like to burn my calories while climbing not while harnessing up. I plan to now return the small, go into a store and try other brands for a more reasonable fit and hopefully ... MoreBased on the sizing specs, I tried this in a Medium, but I could not fully tighten up the waist and legs (kinda loose; not 'safe' snug).

I plan to now return the small, go into a store and try other brands for a more reasonable fit and hopefully somewhat easier on-off mechanics. Other than this issue, which I admit might be unique to me at 165 pounds, 5'10", 32 inch pants size, generally trim and fit but--being in my 60s--not sporting rock hard abs, this would be a fine harness for the gym climbing I want it for. My recommendation would be to buy in person if possible or be prepared for some return-and-exchange shenanigans (which, thankfully, REI does make incredibly easy).
For a first harness or general harness this one is great. Comfortable for long hangs, durable, intuitive. For sizing, I am a 32 waist and ordered a large, probably should be in a medium as I have to tighten all the way to make it fit.My concerns with it are size of gear loops. Fitting a whole trad rack on these loops would be ambitious. I would not recommend it for mutlipitch either. However, if you are looking for a gym harness, capable to transitioning to outdoor TR/sport, and with good comfort and durability, this is an amazing option.
Used for indoor climbing. Very lightweight and sturdy; does what it’s supposed to. Only used a few times, so can’t comment on the durability. My only minor issue is with the sizing. I sized up to an L based on reviews and measurements, although my usual size is an M. I should have gone with the M, though, because I’m at the tightest fit for the L. It still fits fine, but I think I could have customized the fit better with the M.
