A jiu jitsu gi is a training uniform for a jiu jitsu fighter. It is similar to a judogi, but it has tighter cuffs on both the jacket and the pants. This allows the wearer of the gi to benefit from a tighter fit with less material for his opponent to grab. Like judo, the jiu jitsu gi is often referred to as a kimono.
Jiu jitsu is a Brazilian martial art and self defense technique that emphasizes ground fighting and grappling. Jiu jitsu techniques were derived from Kodokan judo in the early 1900s. By using proper technique and leverage, a smaller weaker person can defend himself against a bigger, stronger attacker by using joint locks and chokeholds.
Just like other martial arts uniforms, the colors of jiu jitsu gi are regulated. Only black, white or blue are allowed. In some jiu jitsu organizations it is customary for fighters with white belts to wear only white jiu jitsu gi. Once the jiu jitsu practitioner obtains a blue belt, he is then free to wear any color of jiu jitsu gi.
Article 8 of the Brazilian Jiu Jitsu Federation Rules regulates the jiu jitsu gi:
1. The Brazilian jiu jitsu gi material must not be excessively thick as to obstruct an opponent. It must be made of cotton or similar material.
2. The colors must be white, black or blue and cannot be combined colors.
3. The jacket must reach to the thighs and the sleeves must reach to the wrist.
4. The jiu jitsu gi belt must be between 4 and 5 centimeters in width and be tied securely around the waist to keep the jacket closed.
5. Participants are not allowed to compete with a torn jiu jitsu gi or one that is not in regulation.
6. A jiu jitsu competitor is not allowed to paint his gi except in the case of team competitions.
A jiu jitsu gi can be purchased from a martial arts supplies store or online.
