Navy caps, also known as sailor caps or dixie cups, are a type of headwear traditionally worn by members of the navy. They are typically made of white cotton or polyester and feature a flat, circular top with a stiff brim. The design is practical, providing shade and protection from the sun while also serving as a symbol of naval service. These caps often have a black ribbon or band around the base, which can display the name of the ship or unit. Navy caps are not only functional but also represent a long-standing maritime tradition, often associated with the sailor's uniform.
