You gonna have them at the cook out?? If so XXXL for me since you said they run on the small side
No 3X right now....And - maybe they are not a full size small - ACW3 can give you input on his feeling about the size-trueness.
I am working on an alternate source for 3 and 4 X sizes, but the price becomes crazy.
And - Sparky: I am working up a slogan for the front of the Tee shirt for the FSB next.
I fill out a 2X pretty well (no comments, Tee). Since they are cotton, they will stretch a bit. In my case the shirt is not too tight, but I could use a
little more room. After a while, you don't even notice that you can't breathe.
