1. Fabric and Material

There are different aspects of BJJ-Gi material quality that come under the purview of IBJJF rules. For all these aspects the bottom line is that the material should be such that it allows good gripping.

1. Type of Material: Cotton or cotton mix like cotton-polyester is acceptable as the material for BJJ-gi.  

2. Special Requirements of JAM: i.e. Juvenile division, Adults division, and the Masters’ divisions- Woven fabric is used in making uniforms for these divisions. It may be single, double or gold weaving, etc.

3. Special Foam Material On Collars: EVA or ethylene-vinyl acetate foam is a good replacement for rubber or vinyl. It helps in improving the durability and gripping around the collars.

4. Patches: They too should be made of the same material as the Gi like cotton or cotton-mixed fabric.

2. Colors and Shades

1. You can wear White, Royal Blue, or Black color uniforms. Moreover, it is important to note that both players have to wear a different color Gi in a match. Therefore, it is important to have at least two uniforms of two different colors.

2. The second important rule is that the complete Gi should be uni-color. It means that the uniform can’t have different colors of top, collar, and trousers.

3. BJJ belt color is an exception. The belt color is decided by the qualification level of the player. For adults, they are White, Blue, Purple, Brown or Black. Click here to learn more about the BJJ belt level system.

The purpose of the belt is for identification of the rank of the BJJ practitioner as well as to hold the Gi at its correct position.

The belt is wrapped around the waist over the jacket. Tying with a double knot ensures that the belt is sufficiently tight to hold the jacket.
