MMA Gloves and Apparel

Anyone know the sizing for these gloves? or where to find it?
Not sure if I need a S/M or a L/XL

Just a slight clarification on MMA. It actually hasn’t been around since Ancient Greece. It’s only been around since 1993. However, wrestling HAS been around since Ancient Greece, and from the very first Olympics. Wrestling is only one discipline used in MMA (Mixed Martial Arts). Other disciplines include: boxing, Muay Thai, Tai Kwon Do, Judo, Karate, Sambo, Kickboxing, and a few others.

I was just excited to see MMA and UFC products listed!!! Yeay!!

I don’t have anything to do with MMA beside watching it. Will wearing one of these shirts would get me beat up for showing off the wrong way ?
