To use this cap, simply adjust the double snapback closure to fit your head comfortably. You can wear it for beach outings, casual walks, or any outdoor activities. When it comes to maintenance, 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. Don't machine - wash or dry - clean this cap as it may damage the vinyl design and the fabric. Store it in a cool, dry place when not in use to keep its shape.
