To wear this cap, simply adjust the double snapback closure to fit your head comfortably. The adjustable design means it can fit most head sizes. When you're not wearing it, you can store it in a cool, dry place. Avoid exposing it to excessive heat as it might damage the vinyl design and the soft - touch heat transfer. For cleaning, use a mild detergent and gently spot - clean the dirty areas. Don't machine - wash it as it could ruin the hat's shape and design.
