In the billiards variation of the same name, the 9-Ball is the money ball, the one that wins the game. In this case, you're going to win whatever game you play in the Central Coast Surfboards® Nine Ball Trucker Snapback Hat.
Light weight, breathable, perforated back is comfortable, provides added sun protection, and is classy enough for the links. Adjustable snap-back closure lets one size fit most.
