A combination of favorites: compact weather-shedding Nano Puff® insulation to protect and warm crucial areas, and high-loft R2® fleece everywhere else. PrimaLoft® Gold Insulation (60-g, with a recycled polyester shell) covers the front and back torso and the tops of the arms, from shoulders to cuffs, for concentrated warmth; meanwhile, compressible and stretchy R2 fleece insulation covers the sides, lower torso and underside of arms and breathes without restriction, enabling high reaches on cold-weather rock walls and unrestricted pole plants on frigid ski approaches. A soft, wicking interior storm flap and zipper garage at the chin gives next-to-skin comfort, elasticized cuffs and hem seal in heat, and a high collar with brushed tricot warm the inner neck and chin. The two zippered handwarmer pockets ride high (harness and pack compatible) and the full-length, reverse-coil front zipper is backed with a low-bulk wind flap and treated with a DWR (durable water repellent) finish.
