Evo Patagonia R1® Air Zip Neck Top - Men's

The Patagonia R1® Air Zip Neck Top is a highly versatile layer for high exertion activities in cold weather. Throw it under your shell, your puffy, or wear it as a stand-alone, there's not much the R1 can't handle. Think of it as an extension of yourself - warm, breathable, quick-drying, and oh so soft.
