IBJJF Uniform Rules

No-GI Jiu-Jitsu Uniform Requirements

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 color(belt) to which the athlete belongs. Shirts 100% the color of the athlete’s rank (belt) are also permitted.

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


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).


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.
