    Momentum Harness

    You're getting the hang of climbing quicker than you thought, and as nice as it is to feel the sweat of your rental harness's previous occupant, the Black Diamond Men's Momentum Harness is a cleaner alternative. This is Black Diamond's best-selling harness—not just for the price point—due to its versatility in the vertical realm. It's on the comfier side of Black Diamond's massive harness collection, appealing to both beginners at the gym and advanced climbers hanging on multi-pitches alike. It's fully adjustable to ensure a secure fit whether you're wearing summer or winter attire. Unlike most beginner harnesses, the Momentum has a haul loop to accommodate big wall adventures a little better.

    Size Up, Good Starter Harness

    • Familiarity: I've used it several times

    I bought this harness for my husband who is just getting into climbing with me, and I have the female version and enjoy it. He's usually a M/L, and I followed other reviews, sized up and ordered an XL for him -- he says it fits great and he feels secure (an important thing as he's still getting over his fear of top-roping). I did notice on another site that reviewers talked about the harness not being breathable if you run hot and I don't know how it is for my husband (who runs hot), but mine certainly gets sweaty when I climb; just something to note. Otherwise, I think it's a great value and excellent harness for beginning climbers!

    size up perhaps?

    • Familiarity: I've used it several times

    Cycling is my main deal but I'm getting into climbing. I'm a medium in most waist/gear things but needed to size up to get these around my bigger thighs. Otherwise works as intended for my trips to the climbing wall so far.

    Good but runs small

    • Familiarity: I returned this product before using it

    This is a great harness it would have done the job for top rope climbing however my husband tried it on and he is a lifter so his thighs are pretty large and the medium size did not fit, it ran a bit too small. I would size up if you are on the larger end of a medium size in bottoms. He is about 5'10" at 175lbs

    First timer

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

    Got to try this harness out for my first time top roping in the gym and it worked great. The medium size snugged all the way down fit me well (31 waist and 21 thigh). I ended up doing some lead climbing outdoors and had no issues loading up with ten quickdraws and a personal anchor. I might try the small for a more snug fit.

    Great harness

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

    Love this harness! I'm new to climbing and thought it was very comfortable and easy to put on, tighten, and loosen. Black Diamond is one of the leaders in climbing equipment, and their commitment to quality shows in this details of this product. The stitching, fabric, and accessories are made of high-quality materials and I trust it with my life!

    one awesome piece of gear!

    • Familiarity: I gave it as a gift but have feedback to share

    Bought this for a friend. These are his words:The black Diamond Momentum Harness is one awesome piece of gear! Not only is it super light weight and comfortable, but it’s construction is confidence inspiring at a very reasonable price point.

    A great gift

      I bought this as a gift for my boyfriend since he just started climbing and it was perfect for what we do for indoor climbing. He would prefer something a little more secure for outdoors, but as it slowly warms up we will decide to buy a different harness by then.

      Great Harness

      • Familiarity: I've used it several times

      Overall, works very well, and does the job since I'm not dead yet. However I do notice that it doesn't fit as snug as I'd prefer. Seems to be slightly off or crooked at times and needs realignment. I haven't had this issue with older harnesses.


        This is a sweet harness and you really can't beat the quality for the price. It is super comfortable and you can tell that it is reliable. I do wish that I would have upgraded to the Momentum DS though, i find the harness wanting to be a bit crooked more than I would like.

        Sweeeeet deal.

        • Familiarity: I've used it several times

        If you're a 33 waist, go with a large! I tried the medium and although it was fine on the thigh, the waist adjustment was maxed. Once you've got the right size, it's a super simple harness for an awesome price.

        Worked phenom for sport climbing.

        • Familiarity: I've put it through the wringer

        I've done multi-pitch in them, trad climbing, sport climbing and taken HUGE whips with this harness. I've got 2 of them currently. For trad climbing, I need to take a gear sling for the shoulder. It's not very comfortable on multi-pitch so by pitch 6, you could be wondering if you're going to have your legs still at the end of it all and you're also lugging up a shoulder strap of doom. I've taken 30 foot whips with these things and it held together on sport climbs and still use one to this day for simple crag-in and crag-outs.

        Worked great for canyoneering

        • Familiarity: I've used it several times

        I got this harness for canyoneering in Zion. It was comfortable for several long repels and to wear for hours at a time going through slot canyons. It rubbed between my legs and made a weird sound when wet, but that's the only complaint. For the price (I got it on sale) it's hard to beat.

        Great Harness

          When I started climbing this was my first harness and have loved and used ever since. My friends always seem to complain about their harnesses not be comfortable but i could never relate because this is a very comfy one! Recommend!

          Nothing can beat reliability

          • Familiarity: I've put it through the wringer

          I've climbed in the Momentum harness as long as I've been climbing. The gear loops are sturdy, the attachment point in the rear is excellent for chalk bags or walk-down shoes- it's a no frills, get 'er done type harness with everything you need for a great day of indoor or outdoor sport. I wouldn't recommend racking this up with your trad gear, as 4 loops aren't quite enough for all your nuts, cams or whatever else you may have on your rack. There is a package option available for this harness and if you are new, I recommend picking up the package deal with this harness.

          And what is the size of a S around the waist and leg?

          Hey Martha, It looks like the measurements for a Small are-

          Waist -27-30
