Description of Patagonia R1® Flash Pullover - Women's A versatile, highly breathable baselayer (now made with earth-friendly recycled polyester content) for mixed thermal conditions. Brisk fall days and frigid winter belays, worn alone or with layers, the R1® Flash Pullover’s high/low interior grid fabric stretches, breathes, moves moisture and insulates – and is now more earth-friendly, thanks to the recycled polyester content. Sized for next-to-skin performance, it’s still roomy enough to accommodate a thin baselayer. Low-grid polyester stretch panels under the arms and at the wrist and hem decrease bulk and increase breathability. To further reduce bulk, the brushed-mesh internal chest pocket is welded in. 100% recyclable through the Common Threads Recycling Program. Slim, feminine fit.
