Stretchy and highly compressible, Capilene 4 provides superior insulation for active use in cold conditions. Its interior grid structure wicks moisture, trims bulk, and confers great warmth for its weight, while its smooth jersey face slides easily beneath layers. This cold-weather baselayer can double as a warmer-weather outerlayer. Made from 50% recycled (and 100% recyclable) Capilene 4 polyester with Gladiodor\\\" natural odor control. Imported.
