Premium Linen Driver CapThe clean, streamlined silhouette, low profile, and stiff sewn down brim are all features of the traditional driver cap. The design originally dates back to 14th century England, where flat caps were popularized by laborers. When workers began immigrating to the U. S. A. they brought their hats with them, which quickly caught on. Made from 100% premium linen, this driver cap has a sophisticated silhouette that brings understated style wherever you go.
