A bucket hat. This example has two eyelets on each side for ventilation and the brim is angled sharply downwards.

A bucket hat is a soft cotton hat with a wide and downwards sloping brim which is worn by both men and women. The brim offers shade from the sun for the eyes and face. They are usually made from heavy-duty cotton fabrics such as denim, or from canvas. Two metal eyelets are commonly placed on each side of the hat so that it is cool to wear on hot days.

In American popular culture, the bucket hat is associated with the character Gilligan, from the 1960s television comedy Gilligan's Island, who habitually wore one.
