To wear this cap, simply adjust the double snapback closure to fit your head comfortably. The adjustable feature means it can fit most head sizes. When it comes to maintenance, you can spot - clean the foam front with a mild detergent and a soft cloth. For the mesh back panels, a gentle hand - wash is recommended. Avoid machine - washing to prevent damage to the vinyl design and the overall structure of the cap. Also, since it's made to order, be patient during the 7 - 10 business day processing time. Enjoy showing off your stylish cap in the summer!
