Soft, stretchy, breathable and compressible, Capilene Thermal Weight is made of Polartec Power Grid fabric with a smooth face that glides beneath layers and a brushed-fleece interior to warm your core, wick moisture and feel smooth against your skin. It also has between 30 - 92% recycled content and HeiQ Fresh durable odor control to keep you welcome among friends. HeiQ Fresh durable odor control 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. Product features include a brushed-elastic waistband for next-to-skin softness, gusseted crotch for mobility, functional fly and flatlock seams that minimize chafing.
