Designed for the lightweight sport climbing redpoint, ice route or alpine mission, the Black Diamond Zone Harness is a versatile powerhouse. High performance, lightweight and breathable, the redesigned Zone now features our patented seamless Infinity Belay Loop, which is durable, low profile, and eliminates the dreaded belay-loop-shift when the loop-seam catches while dogging a route. Fusion Comfort Technology ensures that you'll have ample support when on the wall, while the stretch woven outer fabric adds breathability.
