How to use: Just put on the cap like you would any other hat. It's adjustable, so you can easily find the perfect fit. Notice: Since it's made to order, it takes 7 - 10 business days to process, so be patient. Maintenance advice: You can gently spot - clean the cap with a mild detergent and water. Avoid machine - washing or using harsh chemicals, as this may damage the vinyl design and the fabric.
