The kids' version of the Momentum has the same features that Black Diamond's adult harnesses have. Its Dual Core construction separates a single strand of webbing to ridge above and below hipbones for a secure fit without much weight, and OpenAir foam cushions the waist with breathable comfort. The self-locking Speed Adjust waist buckle tightens in a cinch while the adjustable leg loops keep it snug—and it even has gear loops so your young crusher can keep track of their mini-rack.
