Which hat brand(s) do you favour?
There are so many out there - Resistol and the usual suspects (Stetson (which dont really fit me) and many more).
Almost too many to mention, but I like the Shorty's Cutter, many from The Last Best West, straw from O'Farrel, Rand hats, Hally's, Baron Hats, JW Brooks, Tom Hirt, Dave Brown, Charlie 1 Horse, Raffia straw hats (and sadly many more, LOL. Did I mention, that I like hats? ;-))
