Campaign hat

A campaign hat, sometimes called campaign cover, is a broad-brimmed felt or straw hat, with a high crown, pinched symmetrically at the four corners. The campaign hat is occasionally referred to as a Stetson, derived from its origin in the company's Boss of the Plains model in the late 19th century.

The hat is most commonly worn as part of a uniform, by such organizations as the Royal Canadian Mounted Police, the New Zealand Army, United States Park Rangers, and Scouts. It should not be confused with the Stetson style cowboy hat, which is also based on the Boss of the Plains but has a different brim and crease, nor a slouch hat.
