so far so good

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.

Buckles hard to adjust

Familiarity:
I returned this product before using it

Really don't like this harness. Makes me miss my older BD so much. The leg buckles are very difficult to adjust and the harness has a plastic feel to it. Also, the lack of a rear haul line is always disappointing. Planning to return this item.

Epic harness!

I enjoy having the large degree of adjustability. I can loan it to any of my friends with varying body types and all of them can use it just as well. It is plenty comfortable for sport climbing and would be fine for trad as long as you won't need to hang for a super long time. I found I could sit in it for about 15-20 minutes before I had any issues. Overall, I think this is a really great harness for beginners with a wide range of applications that eliminates most of the guesswork surrounding harness sizing. I would reccommend the Momentum 4s for sure!

Super simple high quality harness

I’ve owned several of these over the years. High Quality. Durable for its features and materials. I’ll probably keep buying.

Great beginner harness, comfortable and adjustable

Great beginner harness for gym climbing. Step right in and with a few quick adjustments, you’re ready to go. Padding seems great. No complaints at all. Thanks BD.

Comfortable and adjustable harness

I bought the L / XL version of this harness. I have a 33” waist but feel as though this harness fits me well. I have used this only in the climbing gym but really like the fit and comfort it provides.
