It is a hat, much like a derby hat. The hat itself has a mostly rounded crown, although it does appear to be slightly flattened. The sides of the hat extend straight down from the rounded crown onto the brim, which is fairly narrow and close in to the crown. The brim curls up slightly at the sides.
