A decked-out kids’ harness built for up-and-coming rock monkeys, the Black Diamond Wiz Kid packs all the features of our adult harnesses in a smaller size. Just like our Momentum and Primrose harnesses, the Wiz Kid 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, our 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.
