I think the patent just ended a couple weeks ago. Ricky Crain is advertising a new shirt in this month's powerlifting USA, and Karin is my choice for a shirt. I also hear Titan is coming out with a shirt, though I don't know any particulars, and I bet Frantz will be coming out with his shirts again.
I think that Chris Confessore, and maybe Jamie Harris were fans of Frantz denim.
