Patagonia Mens R1 Full-Zip Jacket - It stretches, breathes, wicks, and warms - no wonder so many serious trail and mountain athletes use and abuse our R1. And the full-zip front makes it even more versatile, from a midlayer in winter to a lightweight jacket on early spring mornings and alpine summer evenings. The high/low interior grid polyester enhances compressibility, airflow, insulation and dry time, and the jersey microfiber face allows smooth layering. Two zippered handwarmer pockets sit above the harness line and have glued-in (no seams) internal mesh pocket bags. Recyclable through the Common Threads Recycling Program.
