Great for Price

  • Familiarity: I've put it through the wringer

I've owned 3 of these so far and I've loved them. They are durable, simple, light enough and comfortable enough. I'm sure you could spend more and get something that is lighter and more comfortable, but for the price you cannot beat this harness.

Absolutely love it

  • Familiarity: I've put it through the wringer

To be honest I've tried other harnesses on and I just can't get anything as comfortable and durable as this one. It's so good I now have 2! One for the gym and one for outside. It seems to have everything right for me. Good support on my back and no circulation cutoff when hanging. Have used it for 4 years so far. Will keep on using them as both haven't shown any significant wear at all. Washes well too.

Absolutely love it


  • Familiarity: I've put it through the wringer

I primarily used this harness for sport climbing. I really like the fit and feel. It had just enough padding to be comfy but light enough to not really notice it while you climbed.

Unfortunately mine met an untimely death after accidentally getting clipped into a gear loop on the wall. But for the two years before that I loved this harness. I only used this harness outside and it was well loved. I will definitely be picking up another one here soon.

I am 6'2 175lbs with 33in waist I wore a M and i fit great


Year-Round Comfort and Safety

  • Familiarity: I've put it through the wringer

The Black Diamond Aspect Harness was and is everything I was looking for in a harness. Light, durable, and I don't mind spending the entire day in it. Fits small.

Great all rounder.

    I have used this harness for two days now ice climbing and so far it has been great. My one complaint and I am sure I figure it out is that it can be tough to get the waist belt to release when removing the harness. However the leg straps feel very substantial as does the rest of the harness.

    gets you to all aspects

    • Familiarity: I've used it several times

    This harness is amazing. I am just getting into climbing and needed a harness that could help me climb in both summer and winter. I really like the comfort of this harness and how lightweight it is. The mechanism to tighten this harness can be a little difficult to figure out how it works but once adjusted it is perfect. I got a medium originally and exchanged it for a large. I would recommend sizing up in this if you plan on using this in the winter.

    gets you to all aspects


    • Familiarity: I've put it through the wringer

    Very comfortable as long as you have the straps tightened correctly. Every once in a while I will have the leg loops too loose or too tight and I will feel pressure on my hamstrings during falls. Other than that it is very convenient to get in and out of, you can just loosen the loops and just step out of the harness rather than undoing the loops altogether. This just makes putting it on and taking it off faster.

    I was in between the medium and large sizes, right on the upper limit of medium, but just on the lower limit of large. I ended up getting the large after trying the medium, and the fit is great.

    I have been using this harness about 4-5 days per week for the last 5 months and it is still in good shape. No wrinkles or loose threads, or kinks in the stitching.

    Great Buy

      Comfortable Fit. This harness is very comfortable. I let a first time climber try this one out first. they said they had a difficult time adjusting the leg straps to fit snugly around their thighs. Once they figured out the tightening mechanism they still felt they could not get it tight enough. All in all we were able to get it to a safe tightness and they felt safe, secure and comfortable climbing for their first time

      Great harness for ice and alpine routes.

      • Familiarity: I've put it through the wringer

      Have use the BD Aspect on ice and snow routes in Colorado and in the Cordillera Blanca, as well as rock routes in the North Cascades. The fit is great and the harness is very comfortable. Works great with Petzl Caritool Ice Carabiners. A good all around alpine harness, but not something I would use regularly in a gym setting. It would work, but I'd opted for something with more padding.

      I'm 6', 175lbs, and have a 32" waist. Purchased a large.

      Fits small

      • Familiarity: I've used it several times

      I bought a size small, my waist size is 29, and it was too small. I'm going to exchange it for a medium. Other than the sizing issue, what a great one-quiver harness. It can do it all! Comfy enough for multi-pitch routes and light enough for alpine ascents and sending hard sport routes. Overall a great harness by black diamond and look forward to trying the larger size.

      Runs small

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

      Because of how the gear loops are positioned on the harness, you need to be at the bottom end of the size range for it to properly fit (i.e M = 30 in waist; L = 33 in waist). I wear 32 x 32 jeans and needed to buy the large.

      Not for the tall and slim

      • Familiarity: I've put it through the wringer

      So, I originally got this harness for myself but ended up letting my little brother use it. The seat was unbalanced for me to feel comfortable sitting back in. The harness itself was very well built for the price and has plenty of room for your gear. If you are tall and slim I would recommend going up to a medium.

      My favorite color is blue...

      • Familiarity: I've put it through the wringer

      I really like this harness. It racks well, it it super versatile, and it does not break the bank. I have used it for a little over a year now, and it has stood up to abuse like a champ. My only complaint (and the reason that it gets 4 stars) is that it is not the most comfortable harness to hang around in for hours on end. Now, are you going to get a better harness for the price? Probably not. Would this be my first choice for a long, drawn out multi-pitch climb? Nope.

      Could someone plz tell me what this blue cord is for I try using it for my chalk bag but right now I have it tied on with a piece of paracord.

      Use it for whatever extra gear you want to have, but out of the way. My buddy uses that spot for a chalk bag. He attaches it with a small carabiner (the kind that is only good for your keychain...not a normal climbing Biner)

      Can anyone explain what the main difference, beside price, between the Aspect and the Xenon? They both appear to be "all-season" harnesses that specialize in ice / alpine. I'm just not seeing what differentiates the $50 difference at full retail. Thanks!

      The Xenos is a bit beefer, which is reflected in its weight?an etra 2 oz. The foam is a bit thicker on the Xenos from what I can tell and the harness belt is a bit wider. The leg straps in the back have buckles on the Xenos, looks like they have some type of hook adjustment on the aspect. The Xenos and included ice clipper for gear attachment.

      I own the Xenos and love it, it is very comfortable, and easy to get on and off. I have used it for a tiny bit of ice climbing, rock climbing, and hitting the gym. It works well for all, but I bought it because I got an insanely good deal. If you can't really tell the difference personally I doubt it will make much difference to you.

      Does the Aspect harness have the slots to put an ice screw holder (e.g. Petzl Caritool Ice Screw Holder, Black Diamond Ice Clipper)?
