A decked-out kids' harness built for up-and-coming rock monkeys, the Kids' Black Diamond Momentum packs all the features of our adult harnesses in a smaller size. Just like the adult versions, the Kids' Momentum features our Dual Core Construction, which uses two slim bands of high-tensile webbing on the outer edges of the waistbelt and a venting OpenAir foam insert in the center to offer breathable, lightweight comfort without pressure points. And for growing kids, the trakFIT leg loop adjustment system uses a simple slide adjuster to quickly and easily adjust the diameter of the leg loop and provide a wide range of fit.
