Whether fitted or adjustable, baseball caps are popular throughout the general population. Wearers can not only support their favorite baseball team, but baseball caps can also be customized with various logos, sayings and colors. Traditionally, these caps are sewn in six sections and topped with a fabric-covered button on the crown. At times, the rear section of the crown is made with a meshlike material. Baseball caps with the mesh backs are also sometimes referred to as "trucker caps."
