Scott,

I recently played rounds at two courses here in St Louis and they both had Titleist t-shirts for sale in the pro shop.  You might want to check some of the courses in your area.

You can find Titleist clothing on the TPI site.

I have multiple Titleist/FJ t-shirts that I have purchased or been gifted.  They are available out there.

You can buy FJ shirts.

Titleist ones I think you have to get lucky and win a contest or continue to participate and be a valuable member of TT, like Timmy Tiger.  

My cousin has a sweet t-shirt that just says "Titleist" on the front that he got from someone who works at Titleist. 

I have a black Titleist T-Shirt with white print. I have looked for others but haven't found any

I have a green one that I won via Team Titleist but that's it.  Wish I could get more of them!  Great lightweight fabric!

I would wear Titleist T-Shirts everyday if they made them!
