A baseball cap is a type of soft cap with a long, stiff bill that may either be curved or flat. The back of the cap may have a plastic, Velcro, or elastic adjuster so that it can be quickly adjusted to fit different wearers. While the baseball cap is specifically associated with those who play the game of baseball, it is often worn as a fashion statement as well as semi practical headgear. It is very popular in the United States and Japan. Traditionally, the bill is worn forward, shielding the eyes from the sun, but it is also often worn backwards or at other angles. People with long hair in a ponytail may pull it through the gap in the cap above the adjustor. Fitted baseball caps, suited to a particular headsize, lack an adjuster. The cap is normally sewn in six sections, and may be topped with a matching fabric-covered button on the crown. Metal grommets or fabric eyelets are often sewn or attached near the top of each of the six sections of fabric to provide ventilation.
