Momentum Harness delivers a secure, supportive fit so kids can climb longer and play harder
What Our Gearhead® Experts Are Saying:
"This harness is perfect for kids getting serious about climbing. It's easy to adjust, super lightweight, and the gear loops mean little climbers can start learning rope management—all with the same comfort as adult harnesses."
The Momentum Harness is built to set young climbers up for every adventure, from their very first slab scramble to leading routes at the gym. With a Dual Core waist that spreads pressure evenly, OpenAir foam that delivers cool comfort, and a quick Speed Adjust buckle, kids always start safe and stay stoked. TrakFit leg loops grow as kids do, while 2 gear loops help them keep track of draws, snacks, or belay tools. For parents, it’s a harness that adjusts easily and inspires confidence from the harness check to the summit selfie.

Here's what customers have to say
The climbing harness is well-designed and high-quality, providing a secure and comfortable fit for a wide range of ages and sizes. It is particularly suitable for younger children around 5-7 years old, with room for growth. However, some larger or older children around 8-10 years old may find the harness too small, even for skinny kids. The harness is praised for its durability, safety features, and ability to grow with the child, making it a great option for introducing kids to climbing.

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

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, 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!

- 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.

What is the range of adjustment on the waist strap? Trying to get an idea of how long this harness will last for a 7 year old before needing to upgrade.
