The fabric has a brushed finish on the inside for warmth and a smooth knit face that glides easily under layers. Features include a turned fabric collar, a low-hem design, and thumb loops for secure hand coverage. Made from 100% polyester Polartec® Power Dry® double knit with Polygiene® technology for permanent odor control. Please feel free to ask any questions.
