This cap is super easy to use. Just adjust the double snapback closure to fit your head comfortably. It's great for casual outings, sports, or just adding a stylish touch to your daily look. Since it's made to order, please be patient during the 7 - 10 business days processing time. When it comes to maintenance, you can spot - clean the foam front with a mild detergent and a soft cloth. For the mesh back, a gentle machine wash on a delicate cycle should do the trick. Avoid using harsh chemicals or bleaches as they can damage the vinyl design and the fabric. Also, don't tumble dry it; let it air dry to keep its shape.
