What kind of cowboy hat does Brad Paisley wear?

Justin wears custom shaped Atwood cowboy hats. I have my custom shaped replica coming in the mail soon. Had to do A LOT of digging around to find this information and I hope it helps.

Note: I can't confirm that he wore an Atwood brand hat on the Small Town USA tour (his first CD) but you can match up the hat band and the ventilation holes from his new CD Outlaws like me pretty well. I hope this helps.
