The Black Diamond Momentum Harness is a comfortable, competitively priced, all-round climbing harness. 

Balancing the often conflicting requirements of comfort, low weight, usability, and durability, the Black Diamond Momentum Harness provides a body hugging fit whilst managing to not restrict movement. The pre-threaded speed adjust waist-belt buckle reduces fiddling and saves time whilst the trakFIT leg loop adjustment system allows for quick and easy adjustment of the leg loops, but without the weight and bulk of a conventional buckle. 

The harness is finished off with 4 generously sized gear loops and a load bearing rear haul loop (doubling as somewhere to clip your trainers for non big wall climbers). We think this is a mega versatile all-rounder harness. Ideal if you're looking for a first harness, or if you are planning on ticking some big numbers in the mountains but don't want an alpine specific harness. The only downside is that the leg loops can’t be completely undone, so if you are winter climbing you’ll have to remember to put on your harness before your crampons. The trakFIT system will give enough adjustment for insulated winter trousers however.


  • Pre-threaded SpeedAdjust buckle on waist-belt

  • Patent-pending trakFIT leg adjustment for easy, worry-free adjustability of OpenAir leg loops
  • Adjustable releasable rear elastic riser
  • 4 pressure-moulded gear loops
  • 12 kN-rated haul loop

BD Momentum Harness

Fits like a glove and the simple buckle adjusters for the highs are very easy to use improving the overall comfort. The waist buckle is one of the 'new fangled' pre-threaded type, which felt odd initially (to me at least being an old has been and one who is used to a 2 inch webbing-type of buckle) but this has also performed admirably and makes tensioning the waste belt easy. A great harness which I would recommend to anyone.

Harness review

If it fits you, this is a great harness for a really cheap price. It's comfy and really light and simple. The leg loop adjusters are light and work really well. Great for sport and light trad, although another gear loop would be handy for big trad.
