Product Description

The Momentum AL gives climbers of any discipline the same comfort, ventilation and durability that Black Diamond harnesses are known for, at a price fit for dirtbags and new climbers alike. We outfitted the Momentum AL with a traditional waistbelt buckle and our trakFIT leg loop adjustment system, which uses a simple, secure slide adjuster to quickly and easily adjust the diameter of the leg loop and provide a wide range of fit. The waistbelt is built with our Dual Core Construction, which uses two slim bands of high-tensile webbing on the outer edges of the waistbelt and a venting OpenAir foam insert in the center to offer breathable, lightweight comfort without pressure points.

    I bought this harness when I was doing mainly gym climbing and it worked reasonably well in that role... There's nothing partiularly special about the harness other than the $. It's pretty comfortable to sit in (not the most comfortable, but decent), the gear loops have held up very well, and it's fully adjustable. I recently took it out on a full day of trad climbing with at least 8 rappels and it still held up to the job quite well. If you aren't doing a ton of long routes or specialized climbing, this is it. At 33" in waist, I'm just over the center of the adjustment range for the medium.

    I bought this harness after recently getting into indoor climbing and getting tired of the rental harnesses (it didn't take long). I really love it -- it's lightweight, extremely strong, and reasonably comfortable when I'm hanging from it, trying to get my grip back on the wall after coming off. The fit is good, the padding is comfortable, and the gear loops are quite strong. I recently brought my camera with me to the gym and wanted some photos of friends climbing the walls. I lashed my camera to one of the gear loops and climbed to the top of an adjacent wall to get pictures. The camera is a Canon EOS 5D Mk II with vertical grip and 24-105 f/4L lens - several pounds worth of camera hanging from the harness and gear loop. No problems!

    There's also a strong fabric rear loop that I'm hanging my chalk bag from, equidistant to both arms.

    So it's a comfortable, strong harness. Surely strong enough to handle my 185-lb * 9.8m/s^2. :-) And I fall a lot, so it's been tested!

    I bought the women's "Primrose AL" version for my girlfriend, which she loves just as much as I love mine.

    Good harness. I'm not into rock climbing like many of the reviews. I am a landscaper and do tree work as well. Thus the reason for this harness. Works great, comfortable sitting in it for lengths of time (200lb guy), and is very secure. I will agree with other reviews tho, order smaller than you think because they run big. Reference---- I am 6'0", 208 lbs, with a 33" waist and I ordered a Medium which fit nicely with room to spare.

    Color Name: Cool GraySize Name: Large Verified Purchase
    This harness rocks! Everything you need for a bargain. A quick note on sizing. I am 6' and was about 190 lbs with a 33 waist when I bought this (in a Large) and I was already at the tightest point of the waist belt. I went with a Large because I have fairly muscular legs (squats) and wanted to give them some room, but I tighten them too to the tightest extent!

    I now weight 178 pounds and really regret not buying a Medium, as the Large is now fairly loose even when tightened to a maximum in mainly the waist, but also the legs.

    So if you are between two sizes, I recommend sizing down, the worst thing that would happen is your harness looks a little offcenter, but at least you will be snug and comfortable on your falls.

    There are several problems with this harness. First, it is not comfortable for me. The harness is painful even while just hanging from it while planning my moves. Second, it is not very durable. The belay loop and the fabric on the leg loops are a bit fuzzy after just one afternoon at the gym. On the plus side, the harness is very light, it does not restrict my movement at all, and is very comfortable to walk around in, but I buy a harness for its climbing performance, not its hiking performance. I upgraded to a BD Big Gun harness after using this once and am glad I did. Also be aware that the sizing is off. My 33 inch waist is on the smaller end of the adjustments of a medium harness.

    I purchased this harness after doing some research. I'm fairly new to rock climbing and wanted a quality harness with plenty of adjustment. First off this harness is built very well with fantastic materials. I read something about someone complaining about the gear loops getting in the way when walking. I'm not sure if they revised the design or not, but I can't hit them even if I try to alter my normal walking pattern.

    Very lightweight, and because its so adjustable I don't even know I have it on which is great when I'm just bouldering at the local indoor gym.

    Highly recommended!!

    Bought this as my first harness (I never buy cheapest as I don't trust "cheapest" to have good quality) when I started gym climbing 6 months ago. I knew I'd be climbing a lot, and wanted something comfortable and useful as I moved to sport climbing when the snow melted. When in the gym working on a hard route, I have no problem falling on it or hanging for a rest. When working harder problems or lead climbing on overhangs, no problem with leg movement. Went outside 2x so far and found the loops well placed and useful. The buckles snug down well and don't get loose. This may be due to the time I spent ensuring proper fit (bought via a local store, not this site). Be sure to measure and know sizing to ensure comfort and safety.
