Made to manage the extremes of high-output exertion, our Capilene Midweight fabric finds the right balance of weight, breathability and wicking. Worn alone or under layers, it keeps you dry and comfortable in cool-to-cold weather. Constructed with Polartec Power Grid fabric, it has a smooth face for easy layering and a brushed-back grid that aids in wicking as well as warmth. Solid-colored fabrics have 66% recycled-polyester content, heathers have 33% and both are treated with Polygiene permanent odor control. Features include a brushed-elastic waistband for next-to-skin softness, gusseted crotch for mobility and flatlock seams that minimize chafing.
