The Rothney is a Raindura style, which means a revolutionary, thermosetting yarn has been hand woven inside this paper straw which is blocked and treated with an ultra light water repellent coating. The result is the most shape retentive, durable straw hat in the market. It's finished with a solid Japanese grosgrain ribbon in the front, and a chambray ribbon in the back. Perfect hat for the beach or by the pool.
