Gi IBJJF Uniform Requirements

The International Brazilian Jiu-Jitsu Federation (IBJJF) hosts some of the biggest Brazilian jiu-jitsu tournaments in the world. These tournaments include the World Jiu-Jitsu Championship, World No-Gi Championship, Pan Jiu-Jitsu Championship, European Open Jiu-Jitsu Championship, and more. The no-gi uniform requirements listed below were created by the IBJJF to level the playing field as much as possible and ensure a high level of competition.

Material

Your Gi 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 Patches & Colors

Cotton, properly seamed, patches are allowed only in authorized regions of the gi which can be found in the IBJJF Rules Book. Any patches that do not comply with these requirements, or in unauthorized regions of the Gi, will be removed by the Gi inspectors

Gi color must be uniform and be either white, royal blue, or black. In addition, athlete’s gi tops and gi bottoms must be matching in color. This includes collars as well

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 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), the width of gi collar (5 cm), the opening of the sleeve at full extension (7 cm)

 

Other Requirements

Use of a shirt under the GI top is prohibited, except for women. In the female divisions, it is mandatory for the use of a stretchy or elastic shirt that hugs the body beneath the GI; It can be short or long-sleeved, without the necessity to follow the color requirements. It is also permitted for athletes to use a one-piece swim garment (bathing suit) or gymnastics top

Wearing pants of any kind under gi pants is prohibited, except for women, who are permitted to use pants made of elastic fabric (clings to body) under the GI pants, as long as these pants are shorter than the GI pants

Athletes must use undergarments. The use of thong-type undergarments is not permitted; only briefs-type undergarments

Gis may not exhibit mending or tears, be wet or dirty or emanate unpleasant odors
