The Momentum AL gives climbers of any discipline the same comfort, ventilation and durability that Black Diamond harnesses are known for, at a price fit for dirtbags and new climbers alike. We outfitted the Momentum AL with a traditional waistbelt buckle and our trakFIT leg loop adjustment system, which uses a simple, secure slide adjuster to quickly and easily adjust the diameter of the leg loop and provide a wide range of fit. The waistbelt is built with 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.
