What is the difference between GI and NOGI training? The GI is actually another word for the Kimono. The reason we train with it is because if you are in an altercation you have the ability to grab the clothes and they have the ability to grab yours. So we have to train around the fact that there is grabbing involved. If we were just using street clothes they would get ripped and torn all the time. NOGI means you are not wearing a GI, you are wearing shorts and T-shirt. In that kind of training you wouldn’t grab any clothes. NOGI means you train in the same Jiu-Jitsu but you modify things a little bit because you can’t grab the clothes.
