Less prep time regardless of what you like to climb.

No matter what type of rock you like to jump on, you'll get on faster with the Momentum Speed Adjust Harness from Black Diamond. A SpeedAdjust buckle on the waistbelt combined with the TrakFit leg adjustment system means less time spent fiddling with buckles and more time cruising up your favorite granite. With the harness' Dual Core OpenAir EVA foam waistband, your comfort is pretty much a given, not to mention the low-profile fit and bullhorn-shape make this harness great for wearing with a pack. Four pressure-molded gear loops and a 12 kN-rated haul loop ensure that you have plenty of spots to rack and carry your gear.

Perfect gym harness

  • Familiarity: I've put it through the wringer

Easy, simple, comfortable - for gym climbing. Seems to run a bit small if you're going to use it outside, esp. where cool weather clothing may be more bulky - so if you think you're headed out : consider sizing up if you're on the border of a sizing choice.

Another Great One From BD

  • Familiarity: I've put it through the wringer

I use this harness from BD mostly for sport and gym climbing. It has a fair amount of padding in the hip and legs. The speed adjust makes getting on with your rocky day faster. Can't complain for the price.

Your first Belay-tionship.

    For quality and comfort at an affordable price, the Momentum harness can't be beat. The waist belt and leg loops offer ample padding for long climbing sessions (read: being belay-servant or "hang-doggin' the proj," as my climber wife would say), and the ease of adjustability makes for a custom fit and easy on/off.

    If you're on the threshold of different sizes due to your waist measurements, choose the size up if you're tall. Though the waist belt of the M is a better fit for my 32in waist, the length between the tie-in points of the L is more comfortable at 6'3".

    Safety First

    • Familiarity: I've used it several times

    This is the first harness I have used since I started climbing, two years later, I see no fraying in any of the stitching and it still holds me very solidly. I will say it does take awhile to adjust it to the proper fitting to find the value in it's comfort-ability, but once you find the pocket you can climb very confidently in otherwise the only hardware that keeps you alive. Main usage for said harness is in the gym thus far, and it has seen minimal outdoor use so far.

    Momentum harness

    • Familiarity: I've used it several times

    This is my first harness and I have only used it in a gym. That said I think it will work great when I transition to outside. I ordered a medium and wear a size 30” in jeans. I have to cinch the medium all the way down but I am glad I didn’t order a small. Very pleased with this harness.

    Great harness for the gym

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

    Got this harness just for the gym as I was starting to think my old one was getting too old to be safe. Speed adjust is very convenient. Gear loops look robust. Feels pretty light. Might use it for clipping bolts outside in the future, but it's not going to replace my Misty Mtn harness for trad or any long multipitch climbs.

    First Harness

    • Familiarity: I've used it several times

    I have been bouldering for a while, but I figured it was time to finally get a harness so I can top rope and sport climb. This harness is very comfortable, and a great price! I am about a 32-33 waist and I went with the medium. I am definitely on the upper end of a medium, so 34 waist and up should go with the large.

    Momentum Harness

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

    This harness is a replacement for my old worn out harness and it’s been great so far. A medium fits my 30” waist perfect and it adjusts nice and snug on my waist and thighs. Plenty of loops to hang your draws and anything else you need.

    Dude on rock? Rock on Dude

    • Familiarity: I've used it several times

    Getting into climbing, I was needing a harness. I didn't believe love at first site until I received this harness! This product is extremely great, especially for the price. First of all, can't go wrong with Black Diamond. I was skeptical about the sizing as I am a 32" waist/weighing 145lbs, being in the middle of a medium and a large. Went with a medium and fits perfectly! The waist strap is a normal tightener, but the leg loops were interesting. Instead of having extra strap to pull on, there is a tap you slide left and right to loosen and tighten. Once you get it, you'll understand. That being said, it held its tightness, I didn't have to tighten for each climb. I did have to get used to the waist belt as its twisted left, so the straps open on my left hip. But super cool thing is to have the gear loops closer to the front where I can see. It's a solid investment, completely recommend!

    Comfort on Another Level

    • Familiarity: I've used it several times

    These harnesses are great! Nice wide padding in the leg loops helps to distribute weight when free hanging/rappelling, making it great for climbing and canyoneering. It has adjustable buckles at the waist and leg loops so you can snug up the fit even more before tackling a difficult route. Reinforcred gear loops means your pro is always handy as well.

    Great item with great fit

    • Familiarity: I've used it several times

    It was really hard to get this size in stores but It was here in great price.
    Really nice with great fit.
    It fills very secure and looks great.

    All the right places ;)

      Great beginners harness the fits and feels great in all the right places, feels super secure and the gear loops have plenty of space and are pretty solid. Great snag for the price. Stay sensual.

      Comfortable and Affordable

      • Familiarity: I've used it several times

      Great Harness for the novice climber. Padding is great making heavier falls much more mellow which increases your confidence when climbing. All in all a great harness for the price.
