Just like bandana acts as a barrier to protect the skin and hair people who wear lots of helmets find them equally useful. In all sorts of styles and colors, custom-printed bandanas are available. To ensure the wearer is kept cool on hot summer days some have built-in water bladders that can be pre-cooled in the refrigerator. Pets, mostly dogs, are frequently dressed in bandanas that match with the owner, making it very easy to tell which dog belongs to which owner at the dog park.
