IBJJF Uniform Requirements

Gi Material

Gis should be tailored using cotton or cotton-like fabric only. The fabric should not be so thick or hard as to impede an opponent from gripping it. For juvenile, adult, master and senior divisions, a gi fashioned from woven fabric is mandatory.

It is permitted to wear kimono with EVA or similar material inside the collar, if the measures of size and rigidity regulations provided in the IBJJF Rules Book are followed.

Gi Color and Patches

Gis must be of uniform color.

The following colors are permissible: white, royal blue or black. Gis with tops and pants of different colors are not permitted; nor are gis with a collar that is a different color than the rest of the top.

Painted gis are forbidden, unless the paint is designed in the form of an academy or sponsor logo – and only on regions of the gi where patches are permitted.

Even in cases where they are permitted, the athlete will be obliged to change gis should the paint mark the gi of the opponent.

Patches may only be affixed in authorized regions of the gi, as depicted in the IBJJF Rules Book. They should be of cotton fabric and properly seamed.

All patches unseamed or in unauthorized regions of the gi will be removed by the gi inspectors.

Belt requirements

Athletes should use a durable, 4 to 5 cm wide belt colored according to the athlete’s rank, with a black tip – except for black belts, where the tip should be white or red. The belt should be worn over the top, wrap around the waist twice, and be tied using a double knot tight enough to hold the gi top closed. once tied in a double knot, each end of the belt should hang 20 to 30 cm in length.

Gi Measurements

The gi top should reach the athlete’s thigh and the sleeves should come to no more than 5 cm from the athlete’s wrist when the arm is extended straight parallel to the ground.

Gi pants should reach no more than 5 cm above the tibial malleolus (ankle bone).

The inspection will verify whether the following official measurements are met: gi lapel thickness (1.3 cm), width of gi collar (5 cm), opening of sleeve at full extension (7 cm).
