A sailor hat, also known as a navy cap or fore-and-aft cap, is a type of headwear traditionally worn by sailors. It features a wide, flat brim and a rounded crown, often made from cotton or wool. The design is practical, providing shade from the sun and protection from the elements while at sea. Sailor hats are often associated with naval uniforms and maritime culture. They are sometimes adorned with a ribbon or band, which may display the name of a ship or a naval insignia. Today, they are also popular in fashion and costume design, symbolizing nautical themes.
