This character wears a peaked cap.

A peaked cap is a form of headgear worn by the armed forces of many nations and also by many uniformed civilian organizations such as law enforcement agencies.

The cap has a crown, a band, and a peak (British English) or visor (American English). The crown is one color, often white for navies, light blue for air forces, and green for armies, and may be piped around the edge in a different color. The band can be one color, often black, or can be striped, vertically or horizontally. Most caps have some form of cap device (or cap badge). In the British Army, each regiment and corps has a different badge. In the American armed forces, the cap device is uniform throughout the branch of service, though different variants are used by different rank classes. The peak or visor is short, historically made of leather, or in newer caps may be a shiny plastic. Sometimes it is covered in fabric and may be adorned with embroidered ornamentation.
