Description of Patagonia R1 Pullover Pullover - Women's Desert sandstone, December powder stashes, iced-up corners - whether the sun shines or the snow flies, our versatile R1® Pullover stretches, breathes, moves moisture, and insulates. And it just got better: we worked with Polartec® to fine-tune the high/low interior grid polyester fabric (Polartec Power Dry®) into an updated exclusive that's more breathable and compressible and has an improved feel and durability while still maintaining its warmth. Sized to accommodate light underlayers, the R1 works as a stand-alone top or as a light midlayer. The racerback shoulder-seam configuration enhances mobility and pack-wearing comfort. Recyclable through the Common Threads Recycling Program.
