Several guys have asked about XS shirts. I actuall have a couple hundred "original" Jay Allen shirts that I produced very early in this project. Many of them are the prototypes of the current designs you've seen. I started by using real vintage t-shirts from the 70's and 80's. They are cotton/poly blends like the shirts I'm using now. I stopped using them because it wasn't sustainable...and the sizing was VERY small. Anyone that is interested just PM me. The sizing is all over the board so I would ask that you measure a shirt you like and I'll see if I can match it from the shirts I have made. When these are gone...they are gone for good. My stock of vintage shirts is pretty well used up. I don't have all of the designs on these shirts either. If there is any interest I'll do an inventory and post it.
