I have a polka dot hat, but I don't have one with a short brim like the Rapha Gentleman's Cap, a cycling cap "designed for the urban riding dandy." I love the polka dot design along with the satin ribbon straight down the center of the hat, very fresh. The Rapha cap has fully bound seams and are lined with anti-bacterial tape to wick sweat away and keep your head dry.
There are two other exclusive designs available, see link.
