The Nike Sportswear Therma-FIT ADV Tech Fleece Pants use a quilted variation on our Tech Fleece fabric that embraces the randomness and uncertainty of a busy day. This wonderfully warm variation on Tech Fleece uses fabric panels created to minimize fabric waste--as a result, each style is slightly different. This product is made with at least 75% sustainable materials, using a blend of both recycled polyester and organic cotton fibers. The blend is at least 10% recycled fibers or at least 10% organic cotton fibers.
