What follows are the rules for the IBJJF in regards to kimonos. Keep these in mind if you have read our reviews and are looking to purchase a new gi. Unless you only want it for training, be sure to follow the guidelines. If you’ve never been to an International Brazilian Jiu-Jitsu Federation tournament, you have never seen the gi checks they do. The checks are serious and there is no need to be disqualified ahead of time.
