Heck, if nothing continues to be available, I'm thinking about having a couple shirts and a hat or two made for me by the screen printer that does all my business apparel. Just for my own use though, I wouldn't sell or give anything away.
I designed a bunch of shirts last year and sent off to Diezel about using them. We back and forthed a few times but with everyone being incredibly busy it kind of fell to the side.
Peter - if you're still interested, I've still got the designs. Drop me an email!
