Patagonia

Wicking, warm, and breathable base layer leggings for cold temps

For technical insulation that keeps you dry when you're moving and warm once you stop, the micro-grid fleece interior of Patagonia's Capilene Thermal Weight provides the greatest warmth combined with the greatest breathability of any baselayer in their 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.
