Using this tactical cap is easy. First, adjust the Hook and Loop strap at the back to fit your head comfortably. You can attach your favorite patches to the Hook and Loop panels on the top, front, and back of the cap. When it comes to cleaning, it's recommended to hand - wash it in cold water with a mild detergent. Avoid using bleach as it may damage the mesh fabric. After washing, let it air dry. Don't wring it out forcefully as this can distort the shape of the cap. Store it in a cool, dry place when not in use to keep it in good condition.
