I bought an A3 the paints were too small and the top was too big. I gave it to one of my students who's a a2 and the pants didn't even fit him! it looks awesome but its not! I tried to get ahold of the manufacture no luck. so if you have tiny little chicken legs and a fat upper body it might be for you, I just don't know of anyone who trains bjj who could fit the odd size. I wont make that mistake again ......
