Brand new long sleeved Champion (not the sport's firm I don't think) men's shirt in blue and white stripes. Made from 65% polyester and 35% cotton material, this large size, long sleeve shirt has a collared neckline and button closure for a classic button-up look. I assume that the size 20 means 20 inch collar. See photos. Perfect for all occasions, this regular fit shirt is machine washable for easy care.
