Polyester jersey set. This is a thin jersey, but the lining has a warm finish (please check the images), so it can be used from autumn to winter. It's easy to move in. I've cut off the size tag, so please check the actual measurements in the photos. There is some wear on the metal of the zipper (bottom part). There are also small pills. - Brand: adidas - Color: Blue/Navy - Style: Jersey Set - Design: Full-zip jacket - Material: Polyester - Fit: Relaxed fit Thank you for looking.
