To wear this cap, simply adjust the double snapback closure to fit your head comfortably. Since it's made to order, be patient as it takes 7 - 10 business days to arrive. 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, you can gently brush off any dirt. Avoid machine - washing the cap to keep its shape and the design intact. Also, don't expose it to high heat as it may damage the heat - transfer design.
