Inspired by the double-knee work pants early climbers swore by, the Doubleback Twill Pant is built from heavy-duty cotton duck canvas that can take a beating. The high-set, wide rear pockets keep essentials within reach on the wall or on the move, and the double knees add extra life where it counts. Plus, BRCM gave them a wash so they’re broken in from the start, but trust us—there’s plenty left for you to make ‘em your own.
