The Patagonia Women's Capilene Thermal Weight Crew Neck Top is Patagonia's warmest, most breathable polyester baselayer with minimal bulk. It uses Polartec® Power Grid™ fabric with Polygiene® permanent odor control and Fair Trade Certified™ sewing. Like ducking into a warm refugio during the middle of a cold spell, the versatile, toasty Patagonia Women's Capilene Thermal Weight pullover keeps your core temperature regulated and your spirits high even when the weather wants to bring you down. The micro-grid fleece interior of our Capilene® Thermal Weight provides the greatest warmth combined with the greatest breathability of any baselayer in our lineup. Soft, stretchy and compressible, Polartec® Power Grid™ fabric has a smooth face that glides beneath layers and a brushed fleece interior to warm your core, wick moisture and feel smooth against your skin.
