Patagonia's most versatile baselayer: warm, breathable, quick-drying and with HeiQ® Fresh durable odor control for daily use. The Capilene® Midweight Bottoms hit the sweet spot between weight, breathability and wicking performance so you can wear this piece alone or under layers to stay dry and comfortable while fishing in cool weather. Capilene Midweight has a smooth face for easy layering, a forgiving stretch that moves with you and an internal diamond-grid pattern that rests lightly on the skin to trap warmth. The hollow-core yarn construction increases wicking performance and speeds dry times. Treated with HeiQ Fresh durable odor control, which means less washing and longer wearing, and because these bottoms are Fair Trade Certified™ sewn, the people who made them earned a premium for their labor. Features include a brushed-elastic waistband for next-to-skin softness, gusseted crotch for mobility, functional fly and flatlock seams that minimize chafing.
