The fur felt ascot cap is one of the oldest of hat designs that is still worn by men today and for colder months, they pair well with fabrics like corduroy or tweed when you want to add some variety of textures or colors to an outfit. Brands to look for: Wigens, Scala, and Christy’s of London, or if you’d like the most traditional unlined version, Brooks Brothers.
A fur felt cap of mine sold by Christy’s. It has kept its shape fairly well over the past couple of years and unlike the traditional caps, this one is lined in silk. “Hand made” (in China).
