The most versatile polyester base layer. The Capilene® Midweight fabric hits the spot of weight, breathability and wicking that, worn alone or with additional layers, is the essence of versatility. It keeps you dry and comfortable when worn during high-exertion activities in cool-to-moderate temperatures and insulates beneath a shell in cold weather.
