The Patagonia Men's R1 Insulated Pullover stretches, breathes, moves moisture and insulates. And it is the best it has ever been. It uses Polartec® to fine-tune the high/low interior grid polyester fabric (Polartec Power Dry®) into an exclusive that's more breathable and compressible and has an improved feel and increased durability, while still maintaining its warmth. Sized to accommodate light underlayers, it works as a stand-alone top or as a light midlayer. With a smooth, microfiber face for easy layering, offset shoulder seams for pack-wearing comfort and a zippered chest pocket.
