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 Full-Zip 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 snug-fitting hood that stays comfortable under a helmet, a front zipper for quick temperature regulation, a soft zipper garage to keep your chin comfy and stretchy cuffs that stay put over your forearms. With an exterior left-chest pocket, two drop-in low-profile handwarmers (right pocket has a hidden internal zippered pocket for securing valuables) 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 Full-Zip Hoody earned a premium for their labor.
