As some of you know, I'm not American and neither is my wife. My wife's mom and her boyfriend live in Europe and he's quite the hat afficionado, regularly wears one. As we're in the US, he's asked us if we could get him a nice cowboy hat. Perhaps I offended some with the term "cowboy hat", if so, my apologies, it's the only expression I know for them. In any case, I looked around and there's a ton of different options and styles. I guess they're different in every region, but I'd like to have some opinions on what to get and what not. Budget is not endless, so any good recommendations are welcome. Also, which types are definitely a nono or other useful advice is highly welcome.
