Patagonia Capilene Thermalweight bottom
The micro-grid fleece interior of the Capilene® Thermal Weight provides the greatest warmth combined with the greatest breathability of any baselayer in the lineup of Patagonia.
Soft, stretchy and compressible, the 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.
