To wear this cap, simply adjust the double snapback closure to fit your head comfortably. The adjustable feature ensures a snug fit for most people. When you're not wearing it, you can store it in a cool, dry place to keep its shape. As for cleaning, use a mild detergent and gently hand - wash the cap. Avoid using harsh chemicals or putting it in the dryer, as this could damage the foam front and the vinyl design. Since it's made to order, be patient during the 7 - 10 business - day processing time.
