Lightweight, highly breathable and moisture-wicking, the R1 Full-Zip can be worn alone or underneath a shell jacket for alpine ascents.

Product Information
It stretches, breathes, wicks and warms - no wonder so many serious trail and mountain athletes use and abuse Patagonia's R1. And now it's even more versatile, with a full-zip front making it easier to use for everything 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.
