    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.

    Momentum Harness

    • Familiarity: I've put it through the wringer

    The size fits perfectly as well as remains very comfortable. I took a pretty decent fall before the slack caught up, (15+ feet) and it was a very comfortable fall. Always have your belayer paying attention! I use indoor and outdoor all the time and it performs as expected from Black Diamond. The price for how well this harness performs is stunning!

    It's a solid harness

    • Familiarity: I've used it several times

    I picked up three of these for my friends for a canyoneering trip we are taking in Zion in a few days. I've had great experiences with this harness in the past and don't see any reason I won't continue to have them this time around.

    The harness is comfortable, fits as described, and is a great value for the price charged. I've never had any comfort issues with this harness, and it is well constructed. If you're looking for an inexpensive starter harness, this is a great choice.

    Great all around harness!

    • Familiarity: I've put it through the wringer

    I've had my BD momentum for over three years now and I just retired it for another momentum. This was my first harness and I used it for everything from cragging, challenge course facilities, SPI work to all day multipitches. It is very affordable and you really don't need much more. I trad climb 95% of the time and it has enough room for a double rack and I also wear it in on long approach hikes with gear on it and it's still pretty comfy. Hanging belays aren't the most comfortable but it's better than plummeting to my death so.. my brother has a big wall harness and I've sat in it so see how much more comfy it is and for the price difference I can't say it's that much more comfy. I would recommend this harness to anyone starting out to anyone looking for a new harness after wearing another one out. You can buy this affordable harness and spend the money you saved on new gear or gas to the crag. I am a 35 waist and I have an XL.

    High on performance, low on price.

    It's amazing that this harness is Black Diamond's "bottom shelf" harness, because it kicks ass without busting my bank. I've worn this harness ever since I started climbing in gyms, and now I take them up big walls even though they aren't necessarily big wall harnesses. As far as comfort is concerned, climbing was never supposed to be comfortable, and it gets the job done. Don't get me wrong though, this harness isn't like tying a rope around you like the good old days; you'll stay relatively comfortable.


    • Familiarity: I've put it through the wringer

    First of all, this is a relatively inexpensively harness. The harness is fairly light weight and the gear loops are big enough to carry a standard double rack. Not a huge fan of the speed adjust at first, but it's fine now that I'm used to it.

    I found that the harness is uncomfortable for even semi hanging belays or belaying heavy people. Specifically, the waistband rubbed painfully on the top of my hip bones. None of my past harnesses have caused discomfort.

    The harness is somewhat bulky. This is noticeable when stuffing it into a pack and when climbing/sitting in it.

    This harness is fine for short cragging days and non extended use. Wouldn't reccomend for multipitch routes or long trips. I'll be buying a new harness in the near future.

    Great Starting Harness

    • Familiarity: I've used it several times

    I use this harness about 6 days a week about 3 hours each time at the indoor wall at my school for top rope and lead. I works great for both and is extremely comfortable and light weight. It also keeps me attached to the rope when I drop 20 feet from the top. This is a great harness.


    • Familiarity: I've used it several times

    I have gone through 4 harnesses now and this is the first one I know I am going to buy again. It is comfortable right from when you first take it out of the package and defiantly was made to last. I was a little disappointed it didn't have a good place to actually attach my chalk bag like my last one but most harnesses don't these days. Overall very pleased.

    Step up

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

    I started out with a Black Diamond Momentum AL Harness, I wish I'd skipped that and gone straight to this one.

    Super comfy, easy to adjust, great price per quality ratio.

    Great harness, great price.

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

    Got this during the recent site wide sale, which brought this down to $43. Used it the first day, love the speed adjust features, as sometimes I do share it with friends. Build quality seems to be quite nice as well. I've only used this inside the gym, but plan on taking this outside as well.

    Runs small

    • Familiarity: I returned this product before using it

    I'm 5'5" with a 30 inch waist with a normal build. I order this harness in a small and the leg fit was way too small. Had to return and order a medium. The company did send me a free UPS mailing slip.

    How is the sizing?
