TITLEIST "Team Titleist" Castle logo adjustable hat

As you can tell from the pictures this hat has not been used and is in new condition. It's fully adjustable so it will fit practically any hat size. It's got a Castle logo on the back above the adjustment strap but we haven't been able to identify the golf course, club, brand or team that it's associated with. If you recognize the Castle character PLEASE let us know! The hat is a Dark Navy blue and goes well with everything. Make an offer, we say yes a lot. Also, we've got nearly 400 other things at fbmp under PHAP Thien for sale so take a look!!! Thanks guys we appreciate your help.
