What is a Baseball cap
The baseball cap is probably the type of cap that people use the most today. It began to be used in the early 20th century to protect baseball players from the sun and has since become a very strong popular cultural symbol. It is made up of several sewn-together pieces of fabric, but has a tighter fit and a larger visor than, for example, the Newsboy cap.
