A decked-out kids&'; harness built for up-and-coming rock monkeys, the Kids&'; Black Diamond Momentum packs all the features of adult harnesses in a smaller size. Just like the adult versions, the Kids&'; Momentum features 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.
