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.

Perfect Harness, Great Price

By David

from Tulsa, OK

Comments about Black Diamond Momentum AL Harness:

This harness was everything I wanted. The speed adjust tightening mechanism is very handy and this harness has worked perfectly for both indoor and outdoor climbing. The gear loops have plenty of space and overall this harness is great value for the low price point.

Primrose SA Harness- Womens

Comments about Black Diamond Momentum AL Harness:

I have been climbing in this harness for a few weeks now and I absolutely love it! This Harness is incredibly comfortable and has not been restricting on any of the climbs thus far.


great harness for the gym

By Matthew

from CA

Comments about Black Diamond Momentum AL Harness:

A great harness for the climbing indoors. The speed adjustments are great. A few nits: I do miss from the original Momentum model was the velcro strap. The new leg strap adjustments take a bit of getting used to--not as convenient as the original Momentum harness IMO. Still a great harness overall.


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

By Lily

from Undisclosed

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

By Aidan

I'm just getting into climbing and needed something reasonable to get me started. This is a great package deal! The harness fits me perfectly. The belay device Is basic, but that's all I need. I'd recommend this to anyone.

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!

  • Q:

    in the sizing for the harnesses .... waist size is measurable ... what is to be measured for the "leg" measurement ...??

      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.
