How to use: Simply put the cap on your head and adjust the elastic drawcord at the back to fit comfortably. When you're out running, the mesh will keep you cool and the peak will block the sun. Note: Don't expose the cap to harsh chemicals as it may damage the fabric. Maintenance: You can hand - wash the cap in cold water with mild detergent. After washing, let it air - dry. Avoid using a dryer as the high heat may shrink the cap or damage its shape.
