Thanks to a large range of adjustments, the Petzl Corax II Harness fits well whether you wear it on a summer sport climb or over five layers on a winter mountaineering trip. Petzl designed the Corax II harness with two pre-threaded DoubleBack buckles on the waist to help keep the belay loop centered while allowing an incredible amount of adjustment. The same type of buckles help you adjust the legs to fit extra layers, and releasable rear elastic lets you answer nature's call without removing your harness. Four gear loops, two Caritool slots, and a haul line loop provide plenty of options for racking.
