Does the IBJJF Allow Spats in Competitions?

No, the IBJJF (International Brazilian Jiu Jitsu Federation) does not allow male competitors to wear spats or leggings in either Gi or No Gi events.

Women, however, are allowed to wear spats or compression pants under their gi pants, but they must not be longer than their gi pants. Additionally, women are also allowed to wear spats for No Gi events.

Finally, for women, spats must be black, white, or a combination of black and white, or the color of their belt rank.


Key Takeaways

  • For both gi or no gi events, men are not allowed to wear spats for IBJJF events
  • Women are allowed to wear spats but they must be a specific color, and for gi events, they must not be longer than the gi pants.

IBJJF Uniform Regulations

The International Brazilian Jiu-Jitsu Federation (IBJJF) is known to enforce specific guidelines for their events. So if you are unsure if your gear is IBJJF legal we always recommend bringing spares.

Gi Requirements

In gi competitions, athletes are required to wear a kimono (commonly referred to as a gi) that are either white, blue, or black. Pants must be of the same color as the top and cannot be worn over any other pants, with an exception for women, who may wear pants made of elastic fabric underneath as long as they are shorter than the gi pants. Only briefs-type undergarments are allowed, disallowing thong-type undergarments.

No-Gi Attire

For no-gi competition, the IBJJF requires competitors to wear attire that clings to the body and does not pose a risk of entangling. Both genders must wear an approved rash guard or a tight-fitting elastic shirt that extends to the athlete’s hips. Bottoms must be board shorts or elastic shorts that are tight and without pockets, and they must not cover the knee.

For women, full-length spats are allowed for no gi events, but for men, wearing any kind of spats or leggings are not allowed. Undergarments should still meet the no-thong guideline, with athletes expected to wear briefs-type undergarments for both safety and modesty.

Enforcement of Dress Code

During Weigh-Ins

At weigh-ins, competitors must present themselves in full gear, which is inspected for compliance with the IBJJF dress code. For women, spats can be worn beneath the gi pants or for no gi events, but, again, men are not allowed to wear spats for both gi and no gi competitions.

For women, officials check for:

  • Color: Spats must be black, white, or combination of black and white, or the belt rank color of competitor.
  • Fit: Spats should fit snugly without providing any additional grip advantage and must not be longer than gi pants if worn under gi pants for gi events.

On the Mat Compliance Checks

During matches, referees may perform spot checks to ensure that athletes’ attire adheres to the dress code. This includes checks for:

  • Correct Wear: Ensuring spats underneath the gi pants and do not extend past the allowed length.
  • Uniform Color: Spats color must be the color mentioned above (black, white, or combination of black and white, or the belt rank color of competitor)
