When your objective requires a long approach followed by a 3,000 foot booter up a near vertical couloir, you need a pair of pants with the chops of the Arc'teryx Procline AR Pants. Their three layer Windstopper shell delivers excellent breathabity for the ascent and bucks wind when you loosen up your turns down the apron. A gusseted crotch keeps your legs mobile when the final pitch requires a bit of class three climbing up ice and rock. And since ski edges, crampons, rock, and blue ice can take its toll on gear, the Proclines are reinforced with Keprotec along the cuffs to keep the pants intact. The trim, e3D ergonomic fit is designed to deliver an excellent range of motion and will fit comfortably under a harness when traveling across glaciers. The two thigh pockets are harness compatible, and the zippered hem gussets accommodate a range of boot widths.
