In good vintage condition. There are no tags but it feels like cotton or a cotton blend. Very heavy, chunky, warm sweater. Others I have seen say its from the 70s. I love the stylized wave design! Small mark on right side( shown in pic) have not tried to remove it, and slight pilling and pulling that comes with its age. Not too bad though. Im a size L/XL and this fits me well. Measurements in photos.
