The Curtis Sun is crafted using the revolutionary Raindura® treatment that takes thermosetting yarn and hand-weaves it inside a paper straw hat body. The hat body is then blocked and treated with an ultra-light water-repellent coating. The result is a shape retentive and durable performance hat. The Curtis Sun has a 4" Low Pinch Front crown and a 2 1/2" brim, and is trimmed with a Japanese grosgrain band and Comfort sweatband.
