If the snow flies or the sun shines, the Boys's R1 Pull Over from Patagonia layers and insulates up Castle Crags, over Silver Star corn snow, and traveses an ice choked Forbidden coulior. With its high/low grid polyester interior, this zip fleece stretches, breathes, moves moisture, and insulates. Sized to accommodate light underlayers, it works as a stand-alone top or as a light midlayer. To reduce bulk, the brushed-mesh internal chest pocket bag is glued-in to eliminate seams. The R1 Pull Over is recyclable through the Common Threads Recycling Program.
