Baseball caps are just not for athletes anymore. They are also worn by the US Navy and Coast Guard and a part of their uniform. The command logo is printed in front of their cap, which shows the command affiliation. Men/boys wear baseball caps with their casual day wear. Guys can wear in while hanging out with their friends and family during the day, or to their date during the day, to protection for head from the sunlight. This cap falls under two categories: constructed and unconstructed, they are also known as structured and unstructured. Constructed caps are for athletic teams while unconstructed are for casual wear.
