That is one fine lookin' lid, 40Cal! You've been posting some nice finds, lately. Are these newer acquisitions, or hats you've already got in the dock?
40cal, Supreme is a good name for that hat!
I have several Portis hats. Some lined and some not. The unlined have a tipped in logo on the inside crown. I believe it is glued in. Should be some sign of residual glue or a shadow if your hat was originally liner-less.
I'm not sure if the liner-less hats were cheaper originally. I think they were attempting to make the hats lighter for hot weather use. Any pics of your Portis? I would love to see it!
