The Orsun is made from paper straw treated with our proprietary Raindura® ultra-light water repellent coating. Not only water repellent but also shape retentive. this style has a 4 crown and a 2 7/8 brim. The hat is trimmed with a Japanese grosgrain band overlaid with sheer organza ribbon and then finished with our signature dipped nail and a finely woven sweatband. A favorite amongst those who love being out in nature. this is one terrific outdoor hat!
