Black Diamond Momentum Harness

Colour: Kingfisher
Size: XS

The Black Diamond Momentum Harness is a very popular all-around climbing harness featuring four gear loops, trakFIT-adjustable leg loops and an ultra-comfortable waistbelt.

For all-around climbers who know that time spent fiddling with leg loops and adjusting a pinching waistbelt is time wasted, the Black Diamond Momentum Harness delivers a time-saving design for all styles of climbing. A pre-threaded Speed Adjust waist-belt buckle saves time and eliminates error when tying in, while Dual Core Construction™ puts an emphasis on comfort, even when you’re posted up at a hanging belay. TrakFIT leg-loops easily adjust for cool fall days at the crag or blazing summer days on long multi-pitches, and four pressure-moulded gear loops and a haul loop make this our most popular all-rounder.

Great harness

Solid harness, very light but clearly very well manufactured. Recent date (for those indoor climbing this is important as many walls now require harnesses under 10 years old - best to not have 1 of those years be in the shop!).

Sizing from Black Diamond was accurate - I sized up as I was close to top end of one size and the larger one is on the limit of adjustment, perfectly fine, but I would have been absolutely fine - maybe better - in the size down too.

Great Harness

After having a pervious BD Momentum harness for 14 years I knew I was looking for something similar.
From trying on lots of other brands and models I knew I was going to get this one.

It was both lightweight and comfortable which is a tricky balance to find. Where as the competitor of this being the Petzl Adjama, was lacking slightly on the comfort side. The Adjama was lightweight but when you sat in it, the narrow leg loops i found tend to dig in, on the inside of my thigh.

This harness felt great! I could sit in it, rest, stand, belay climb and take falls on lead all whilst being comfortable. I haven't used it outside yet but I'm sure it'll live up to my old harness.

The new leg loop buckles were a little odd to figure out but after 2 sessions in it, it was very simple to use. The main waist buckle was a standard speed buckle so no issues there.

All round a great harness and very happy purchase. Would recommend to anyone.

Excellent harness

I have only recently taken up rock climbing, and this harness is incredibly user friendly and effective even for a begging such as myself. It fits very comfortably on my waist, the straps are easy to loosen and tighten and I feel very safe when climbing the high walls. Can’t recommend enough

Black Diamond Momentum Harness

Great harness, nice and comfy and hardly tell you are wearing it. For a larger climber it’s great that they come in xxl and it’s really supportive and doesn’t pull to tight when descending.
