Black Diamond's most versatile harness.

Black Diamond designed its Momentum Dual Speed Harness to keep you comfortable whether you're a beginner at the gym or an expert on a moderate multipitch. Its Dual Core Construction consists of two bands of webbing that split around the waist in order to allow maximum breathability and weight reduction without any pressure points. Black Diamond also slid OpenAir EVA foam padding and an abrasion-resistant mesh panel between the nylon shell to optimize the harness's comfort and durability. Two Forged Speed Adjust buckles have raised side rails that help prevent abrasions from the webbing, upturned baseplates that allow an easier lift for loosening, and a rear kick down on the top plates that eliminates any slippage while you climb.

The Momentum also features TrakFit slide adjusters that cinch across your legs securely and simply without the need of bulky buckles. You can either adjust or release the elastic rear riser for an ideal fit and optional drop-seat use. Four pressure-molded gear loops give you plenty of space for quickdraws and cams, and its haul loop is rated at 12 kN in order to ensure you can bring what you need on long climbs.

This is my second harness. I had the black diamond sa forever. I got this one for a more four season use to be Able to add more clothes. The only thing I don't like is that the elastics on the back aren't the clip instead there the slide in kind which is ok. But just a little time consuming.

Great first harness

  • Familiarity: I've used it once or twice and have initial impressions

Got this as my first harness getting into the sport. The slim padding keeps it low profile but fairly comfortable, and the adjustable leg loops are great for someone like me with skinny thighs that has a hard time finding a harness that fits well. Black Diamond advertises this as a great harness for agencies to use for rentals, but I think it's perfect for use around the crag. It's not advertised as an all-season harness (like the momentum al harness is) but as far as I can tell the only reasoning behind this is that there is no ice clipper slot. I see no reason why this harness couldn't be used mountaineering (the adjustable leg loops are great for sizing over extra layers as well).
If you fall between sizes on other Black Diamond harnesses as well, then the dual adjustments on the waist band will allow you to keep your belay loop centered. The large range in possible sizes also makes it a great harness for loaning out to friends who are new to climbing.
I bought this harness directly from Black Diamond on closeout, so I paid significantly less than the regular price of $70. At that listed price I would suggest that you go with the momentum sa (unless, as I stated earlier, you're between sizes).

Pros: large size range, 12kN rated haul loop, one-handed adjustment of leg loops, entry-level price
Cons: limited padding, no ice clipper slot (may be preferable for some), pricier than momentum sa or al

In summary: great entry level harness that should last you years of service in all environments. I would definitely recommend this harness for someone who doesn't fit normally sized BD harnesses or will be sharing their harness with a friend.

Bahbahbah bah I'm loving it.

  • Familiarity: I've put it through the wringer

A super comfortable harness that kills it, the dual adjust is an awesome feature that gives you a range adjustment for a lot of different sizes. A few other great features are the plentiful gear loops to keep your gear on and the adjustable leg loops, from canyoneering to trad climbing this is a great harness.

When will you Stock up on this for size...

When will you Stock up on this for size S/M?
