Momentum Harness

The kids' version of the Momentum has the same features that Black Diamond's adult harnesses have. Its Dual Core construction separates a single strand of webbing to ridge above and below hipbones for a secure fit without much weight, and OpenAir foam cushions the waist with breathable comfort. The self-locking Speed Adjust waist buckle tightens in a cinch while the adjustable leg loops keep it snug—and it even has gear loops so your young crusher can keep track of their mini-rack.

Perfect Progression Harness

The kids had the full body harness to share and we needed to get individual harnesses for a canyoneering trip. They performed very well and should be with them until they get close to teenage years. They love having the gear loop to hang draws and other things even though they aren’t yet leading and just doing top rope.

For 4 y/o and up

Bought it for my son who is around 40 pounds. Tightened all the way it is just tight enough for him to start sending it and still be able to grow into it

Great harness

My kids love their harness. They have a great time and don’t complain at all about the comfort or the way it fits.

Does not fit my 2-year-old daughter

Does not fit my 2-year-old daughter, barely got her in it and it's way too big. She is 27 months old and 25 lb for reference. The momentum harness kids full body does fit her though. I bought both to test them she will eventually grow into it.

I have three of these,

I have three of these, for my daughters age 5, 7, and 9. Fits well, simple, does the job, and lightweight. What more could you ask for?

Easy to use

The harness was easy to use on multiple of my kids given its one-size design. It fits my 6 year old up to my 11 year old. The harness is comfortable and not too expensive.

Toddler size!

Familiarity:
I gave it as a gift but have feedback to share

This harness is great. It's comfortable, functional, gear loops are accessible. But please note that this harness is for toddlers. My 50lb, average-sized 6-year-old barely fits in it.
