Solid Choice
I purchased this harness to replace my old one, which had exceeded its recommended lifespan by a couple of months. I reached out to Black Diamond to ask if they offered a recycling program to properly dispose of my old harness, but unfortunately, they don’t have one at this time. However, they kindly offered me a 30% discount toward a new harness, which I used for this purchase. The harness is great! I am 4’11. 5” and the thighs are adjustable. Corporate, if you see this, I think introducing a harness recycling or trade-in program would be a great opportunity to encourage returning customers while also promoting safety by ensuring expired gear is properly retired and not used beyond its expected lifespan.

Worth it
I used to use the harness that were provided at my climbing gym, they we're uncomfortable around the crotch area and had no waist support. I bought the 'Momentum 4S Harness' not thinking much of it. However these made a huge difference in terms of comfortability, it didn't help me get better but these are breathable, comfortable, simple and durable.

Perfect for using with multiple people
Comfortable and the wide size range makes it useful as a harness to use for growing kids or varying friends that you bring with you to the climbing gym.

Leg loops too small
Bought this as an all-purpose harness capable of going over cold weather gear. Found that the leg loops were too small (even extended) to fit over snowpants, and waste belt was a bit small also. Double check your leg/waist diameter needs before purchasing.

so far so good
- Familiarity:
- I've used it once or twice and have initial impressions
- Size Bought:
- S/M
My 13 year old son bought this so he could use while chainsawing trees. In addition to his tree work, 3 of my kids have been swinging around from the trees securely using this harness. They even got me to swing from the tree with it. I'm 6' tall and weigh 155, but I feel like it could take a lot more weight and thicker legs than mine. And it also works comfortably for the kids, ages 10,12 and 13.
