How to use: Just adjust the strap at the back of the cap using the low - profile clip to fit your head comfortably. You can wear it during training, on match days, or when you're at the clubhouse. Note: Avoid pulling the strap too hard as it may damage the clip. When washing, use mild detergent and cold water. It's best to air - dry the cap to maintain its shape and color. Don't iron it directly as it may affect the fabric and logo.
