Very natural. This elegant Stetson Hatteras is made of wild silk, a "luxury" fabric that has fine, irregular thick and thin yarns. The pastel checked pattern offers a nice contrast to the classic herringbone design of the hat. Its cooling, patented fabric with a UPF rating of 40+ provides an excellent sun protection to make this flat cap a perfect summer style. Closed back, with lightweight lining.
