Our Verdict

The Black Diamond Momentum Full Body is designed using many of the same technologies as the adult harnesses. It's super comfortable and one of the lightest full-body harnesses tested. It has "quality" written all over it, with craftsmanship and a design that is top-notch. The simple design assures kids (with adult help) will have no trouble getting it on and adjusted well. The foam padding is both soft and breathable, and even though the leg loops don't adjust, they did a great job of keeping our testers comfortable - even for extended periods of hang time.

Our Analysis and Test Results

This harness loses a few points in versatility but makes up for it by being a well made, comfortable, and easily adjustable full-body harness

Hanging Comfort


The Momentum Full Body is a comfortable kids' harness that uses the same strap construction as their adult versions, resulting in a harness that disperses the weight of a hanging climber surprisingly well. The leg loops originate from the outer hips and cradles the legs in a way that makes kids feel safe and secure when lowering off the wall.

Standing Comfort and Mobility


Just as with hanging comfort, standing comfort and mobility are also very good. A front buckle keeps the shoulder straps in place and holds the tie in points close together for easy access. We loved the lightweight padding on the shoulder straps, which wrap around to the similarly padded back panel. The whole harness, both leg loops, and upper harness move well with all their movements whether they're climbing, doing homework, or escaping to the fort under the boulders while mom and dad run a lap.

At the base between climbs  a little homeschool action is called. Luckily the harness is comfortable even when not on route.

Features


The Momentum has a simple yet techy design. A front buckle makes getting it on quick and easy for little kids and helps hold everything in the right place while they're not tied in. A small elasticized padded backstrap helps support the lower back when hanging and the way the leg loops originate from the outer hip means elastic risers are not necessary to keep them from sagging.

The pre-threaded speed adjust locking buckles are easy enough for many kids to do themselves.

Versatility


The Momentum Full Body isn't quite as versatile as some of its competition. Not only will it not fit the littlest of kids but it doesn't have any features like gear loops or a belay loop that would help in more advanced climbing scenarios. If more advanced climbing is in the cards, the full-body Petzl Ouistiti harness would be a better choice while still offering a comfortable hang.

Since this harness is super comfortable and supportive to hang in, active kids that are planning on spending a lot of time top-roping at the gym or crag will love this harness. With such a simple easy on/off design and smooth sliding buckles, many kids can throw it on and get it adjusted without help from an adult, other than a safety check over.

Overall a great harness for comfort and security.

Value


This harness has a good value. The comfort alone is much better than much of the competition, which makes it a great deal. Parents will love the super-easy "step in, pull on like a vest, and buckle the front" design that saves them from having to fiddle with tons of buckles, instead, allowing their mini-me to do it themselves. With great attention to detail, it was clearly designed by some of the best in the industry.

Conclusion


Black Diamond did a great job designing this harness. Not only does the harness look quality and high tech, but the padded shoulder harness and leg loops do an excellent job of supporting the climber's weight. Any kid who has a brand new passion for climbing often will love this comfortable, sporty harness.
