I used to play volleyball in my NoGi Jets, but they are very low key with almost no visable logos. I have a CSI MMA shirt and a Ringside Muay Thai shirt. The one time I've worn my MT shirt to class and stopped at the supplement store, I ended up in almost a 30 minute conversation with the huge bodybuilders there. The guy was asking me about where I train and what I thought about Mike Tyson in MMA and about Bob Sapp (vs Nog, and also in K-1). My friend that doesn't train wears alot of Everlast and Full Contact Fighter tshirts, but he's a huge fan of the sport.
