Chuck Liddell and Tito have their shirts of course. I think its the GRAPPLING or FIGHTSPORT magazine that advertises Rodrigo Nog. and Brazilian Top Team t-shirts.
inyaface.com has the TAPOUT shirts and fcfighter.com has the FUll Contact Fighter T-shirts. I had seen Caol Ono in Louisiana with a "Uno Shoten" shirt on and it was pretty tight but I have no idea where to get it.
