Patagonia's new Guide Pants use their best-ever Guide fabric, a Polartec® Power Shield® stretch-woven blend (nylon/polyester/spandex) with Hardface® Technology. Features are pared to the bare bones for technical climbing: pull-on waist (flat front with drawcord, elastic back), three zippered pockets (two front handwarmers, one rear) and articulated knees, no fly. This means that they are a bit of a squeeze to get on, but once on are comfy and very lightweight for such a garment.
