Black Diamond's Momentum AL Harness 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. Black Diamond's designers outfitted the Momentum AL with a traditional waistbelt buckle and 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.

    Great deal

    By Bryan

    from Sterling, VA, USA

    Comments about Black Diamond Momentum AL Harness:

    Can't say anything bad about this package. Has everything I need to climb and it all works great. The harness is very comfy, the carabiner and belay device are perfect, and the chalk is great for keeping away moisture. I will definitely stick with black diamond products as I progress with climbing.


    comfortable, does the job

    Comments about Black Diamond Momentum AL Harness:

    didn't realize it was a men's harness, doesn't say on the website title however, it fits well on a woman the waist belt in front of you is kinda of pulled outward even when you are not belaying; it is just angled away from you a bit; not a problem really, but just appears strange color is actually a dull green, not the best; picture on the website shows a bright yellow? overall, comfortable for a woman, also comfortable on the legs, feels light, yet safe, much more flexible freedom for movement during climbing

    Solid starter harness

    By Michael

    from Philadelphia, PA, USA

    Comments about Black Diamond Momentum AL Harness:

    I've been climbing for about 6 months now. Both bouldering and top rope. This is my first harness. It does everything I could ask and for the price I couldn't beat it. Extra chalk bag and chalk was just a nice added bonus. Pretty solid comfort but only have the gym harnesses to compare too. Overall a really nice buy. I'd recommend it too anyone.


    Each time I've made it to the ground was by choice.

    By Amanda

    from Chicago, IL, USA

    Comments about Black Diamond Momentum AL Harness:

    I think my review summary explains my experience with this harness! Climbed 3 times since purchasing it about a month ago. I'm pleased to announce that I've made it to the ground safely. I will say that being female in a men's harness does have more bunching in the crotch but it personally doesn't bother me enough to complain about it. Overall good comfort in the legs and waist, plus I couldn't beat the price!


    Everything the starting climber needs

    Comments about Black Diamond Momentum AL Harness:

    I just recently got back into rock climbing, so I needed the full kit of gear. This was the perfect starter kit, and getting it on sale was the icing on the cake.

    Fantastic first harness

    By John

    from Sudbury, ON, Canada

    Comments about Black Diamond Momentum AL Harness:

    This is my first climbing harness and it is amazing. Great features, very comfortable on the waist and legs, ample space to clip 'biners to - great product at a great value. Always impressed with my BD purchases.


    Excellent, XXL fits larger guy

    By Julie

    from Julie ordered it for Phil--SW Colorado

    Comments about Black Diamond Momentum AL Harness:

    I am a larger guy, and most BD harnesses in XL don't fit, except the Bod Harness. I tried a Bod harness in XL, and this in XXL, and the Momentum just fits and feels better. The gear loops are farther forward than my old Alpine Bod, so they are easier to use.


    Excellent Starter Harness


    from Ontario, Canada

    Comments about Black Diamond Momentum AL Harness:

    This was the first climbing harness I purchased for personal use. Ive climbed indoor and outdoor with my Momentum and ive had zero issues with it in the 2 years of use. I was immediatly drawn to it for 2 reasons, the buckles and comfort. The quick locking waist buckle conveniently eliminates the necessity of doubling back the belts excess through the buckle. The leg loop sliding buckes adjust easily to fit the climbers thighs and can by tightened or loosened off quickly even with gloves on. I think ill be using this one for a while! For size, I wear a LARGE. I am: 6`0`` 190lbs 33`` waist

        Measure around the widest part of the thigh. The leg loops will typically sit above this point, but you need to be able to step into the harness.
