To use this cap, simply adjust the double snapback closure to fit your head. It's great for wearing during the summer to protect you from the sun. When you're done using it, store it in a cool, dry place. Don't machine - wash it as it might damage the vinyl design and the braided detailing on the visor. Instead, spot - clean it gently with a soft cloth and mild soap if it gets dirty. This cap is made to order, so please be patient during the 7 - 10 business - day processing time.
