IBJJF and No Gi tournament Rules

When it comes down to Brazilian Jiu Jitsu Competition, it doesn’t get any more official than an IBJJF tournament. The International Brazilian Jiu Jitsu Federation (IBJJF) is a company that hosts several of the largest BJJ grappling tournaments in the world. It’s where the most serious BJJ athletes come together to compete against the best.

There are very strict guidelines when it comes to rules and regulations. That includes your BJJ. You have to pass a minimum standard in order to be qualified to compete.

This guide looks at the IBJJF Approved Gi Uniform Regulations to make sure you are competition ready when you step onto those mats!

For Jiu-Jitsu No-Gi, athletes should abide by the following attire requirements:

Gi requirements

Fabric and Material

Your Gi should be constructed with a cotton material or something similar to qualify for IBJJF uniform regulations. Some Gi’s can be made up of a cotton blend like a cotton-polyester. You should be fine with these as long as they have a “cotton-like” feel to them. As long as you are able to properly grip the material, you should be good. No grip technology Gi's are no longer IBJJF legal, if your gi is too difficult to grab it CAN be disqualified.

For Juvenile, Adults, and Masters divisions, it is required that you have your Gi made up of woven fabric (Pearl Weaves, Single Weaves, Double Weaves, Gold Weaves, etc).

Some Gi uniforms have a specialised EVA foam construct in their collar. This allows for a rubberised feel to the collar for improved durability and improved gripping. This is perfectly fine as long as the collar rigidity and size passes the minimum measurement requirements.


The Gi uniform colour is strictly enforced in an official IBJJF tournament. An IBJJF approved Gi uniform requires your Gi to be in traditional BJJ colours only.

You are only allowed to wear white, royal blue, or black.

Painted Gis are forbidden. You might get away with it if the paint somehow signifies your school in some way. But it certainly isn’t allowed to paint your entire Gi to match the IBJJF approved Gi colours.

Keep in mind that some Gi manufacturers provide different colours like green, grey, dark navy, or pink. You might get away with it in some other competition organisations, but these are absolutely NOT allowed in an IBJJF tournament. Some even have different colours for your collar and the rest of your Gi jacket. This isn’t allowed either! Keep it classic!

Shirts and Rash Guards:

Both genders must wear a shirt of elastic material (skin tight) long enough to cover the torso all the way to the waistband of the shorts, colored black, white, or black and white, and with at least 10% of the rank colour (belt) to which the athlete belongs.

Shirts 100% the colour of the athlete’s rank (belt) are also permitted.

Note: For black belts a small red area will be tolerated, but must not decharacterise the athlete’s rank colour.
