Black Diamond Momentum Harness (Astral Blue) - 2019

3 reviews   |  
Astral Blue

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
  • Bullhorn-shaped OpenAir waist-belt built using Dual Core Construction
  • 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

Yet to be used - lockdown and regulation has prevented travel and climbing walls closed. Hope to use shortly. Quality looks good.

Does the job

Nice comfy all round harness. I’ve worn this on redpoint attempts through to guiding clients on mountain adventures. It’s comfy, robust and sits well. A shame mediums are always sold out.

Comfortable lightweight harness

Good value, easy to put on and the leg loops have nifty buckles for adjustment. Lightweight and comfortable it’s prob best harness so far.
