Blending minimalism with unconditional performance, our R1 midlayers are made for stop-and-go, cool-weather layering that keeps you warm and comfortable across the full spectrum of mountain endeavors. The Polartec Power Grid fabric‚made exclusively for Patagonia‚features a high/low interior grid recycled polyester/spandex blend that stretches, breathes, moves moisture and insulates. Lightweight and soft on the skin, the R1 Pullover Hoody has a technical fit that accommodates underlayers yet can be worn as a stand-alone top when conditions permit; it compresses down to practically nothing in your pack. For higher-output use and enhanced mobility, we‚ve incorporated lighter weight, super stretchy grid fabric along the side panels, in the snug-fitting balaclava-style hood and at harness line. Details include a minimalist, deep-venting front zipper for temperature regulation, a soft zipper garage to keep your chin comfy, off-shoulder seams that sit comfortably under your pack straps and discreet on-seam thumb holes for added warmth when it‚s cold. With an exterior left-chest pocket and HeiQ Fresh durable odor control so you stay welcome among friends at the end of the day. Fair Trade Certified‚ sewn, which means the people who made the R1 Pullover Hoody earned a premium for their labor.
