Toby Kieth country music star wears cowboy hats
This can depend on what type of hat you are referring to. If you mean the safety 'hat' that is called a helmet or skull cap. If you mean the hat high level dressage riders where that's a top hat, and if you mean the rounded hat that saddleseat riders wear, that's called a derby (pronounced Darby). And of course western riders wear cowboy hats.
