For dark-o’clock starts, you need technical insulation that keeps you dry when moving and warm once the action slows. 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. This fabric also has 30–92% recycled content and is treated with Polygiene® permanent odor control. Features include a brushed elastic waistband for next-to-skin softness, gusseted crotch for mobility; flatlock seams that minimize chafing.
