The Momentum AL 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. We outfitted the Momentum AL with a traditional waistbelt buckle and our 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.

  • Traditional, fold-back waistbelt buckle
  • Bullhorn-shaped OpenAir waistbelt built with Dual Core Construction
  • Patent-pending trakFIT leg loop adjustment for easy, worry-free adjustability of OpenAir leg loops
  • Adjustable, releasable rear elastic riser
  • Four pressure-molded gear loops
  • 12 kN-rated haul loop



No buckle, no hassle—trakFIT™ is a simple and secure innovation for adjusting leg loops that uses a slide adjuster for quick and easy fitting. To tighten or loosen, simply move the slide adjuster along the leg loop’s webbing. The diameter automatically adjusts and provides an incredibly wide range with no dangling webbing and no chance of mis-threading.

Rated 5 out of 5 by Best for the Price I have had this harness for 2 years (L). Put this through waterfalls, rains, and dirt. (Never had it in snow or ice.) The double back buckle is second nature now, and becomes as fast as a pre-threaded one to put on. After some rough terrain and time, all the gear loops are still fine and harness has great durability for its price. Have used it at least once a weak. August 5, 2014
Rated 5 out of 5 by Great Harness! Perfect for those who love climbing, but have a budget to consider. Looks good, fits great and performs well. Honestly a great buy. June 28, 2014
Rated 5 out of 5 by Momentum Harness I love this harness for teaching climbing. It has all the elements of most other harnesses. However, I think that having to double back the buckle is a great practice for a new climber. Climbing is about taking personal responsibility and building in safety checks into EVERYTHING we do. This harness helps with that. I also love how easily the leg loops adjust. This is a great all round harness for rock and Ice. June 8, 2014
Rated 5 out of 5 by Real Product Evolution Having owned the earlier version of the Momentum AL I can say the new version is a positive design iteration. Dual Core Construction, aka splitting the webbing to the top and bottom of the waistbelt instead of one piece of web padded, truly spreads out the pressure just as well as the generous padding in the Big Gun harness. The Trakfit is nice, I still prefer being able to put a harness on than having to step in, but as it goes it works smoothly. Like it says, this is a great all rock discipline harness. April 19, 2014
Rated 4 out of 5 by Very comfortable harness I am new to rock climbing and have only been to indoor gyms. Therefore my only harness experience has been the rentals. I decided to buy my own and this one from Black Diamond is far more comfortable! Whether top roping or belaying, it is a pleasure to wear. The reason for only 4/5 stars is the waist buckle. I may not be used to it yet, but it is not as easy to tighten at the waist as others. April 4, 2014

Rated 5 out of 5 by Great harness This is my first harness and I feel very comfortable in it and it fits perfectly. The double backing loop on the waist belt is no hassle and the harness in general is really light. February 21, 2014
