This FootJoy button down is made of an extremely light weight easy-care stretch fabric, making it machine washable with minimal to no shrinkage. The fabric is also moisture wicking which moves moisture away from the body for added comfort. Antimicrobial technology eliminates odor. The BV Wings are embroidered on the left cuff. Chest sizing is as follows: S (34-36), M (38-40), L (42-44), XL (46), XXL (48-50). Button down runs true to size (not oversized like FJ polos). Care Note: technical fabric, use cool iron only.
