Black Diamond Zone climbing harness is a versatile powerhouse, designed for the lightweight sport climbing redpoint, ice route or alpine mission. 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. Finally, the contoured fit maximizes comfort for the inevitable big whips that come from pushing your limits.
