When it comes to Brazilian Jiu-Jitsu (BJJ), the gi is an essential piece of gear. But what you wear underneath your gi can significantly impact your comfort, performance, and hygiene. It does not matter whether you’re a beginner or a seasoned practitioner. Knowing what to wear under your BJJ gi is crucial for an optimal training experience.

This comprehensive guide will cover the best options for both men and women. It will discuss the benefits of each and give practical tips to help you make the best choices.

Why Does It Matter What You Wear Under Your BJJ Gi?

• Comfort: Wearing the right layers prevents chafing. Hence it keeps you comfortable during long training sessions.
• Hygiene: Extra layers can act as a barrier. Thus reducing direct skin contact and minimizing the spread of bacteria.
• Support and Protection: Compression gear and rash guards offer muscle support and protect the skin from mat burns.
• Modesty: Adding layers ensures you’re adequately covered, particularly during intense rolls.

What to Wear Under Your BJJ Gi (For Men and Women)

1. Rash Guards

Rash guards are the most popular choice for wearing under a gi, and for good reason.

Benefits:

• Moisture-Wicking: Keeps sweat away from your skin. Thus reducing irritation.
• Compression: Provides muscle support and improves circulation.
• Skin Protection: Prevents mat burns and minimizes bacterial exposure.
• Temperature Regulation: Keeps you cool during intense rolls.

Types of Rash Guards:

• Long-Sleeve: Offers more coverage and better protection against mat burns.
• Short-Sleeve: Provides more breathability. Thus ideal for warmer environments.

Pro Tip:

• Invest in high-quality BJJ rash guards. Such as designed for durability and comfort, like those available at Novakik BJJ.

2. Compression Shorts or Spats

Compression shorts or spats (full-length leggings) are another excellent option.

Benefits:

• Support: Offers support for the lower body during intense movements.
• Hygiene: Acts as a barrier between your skin and the gi. Thus reducing bacterial exposure.
• Flexibility: Allows for unrestricted movement. Hence essential for guard work and transitions.

Pro Tip:

• Choose compression gear with flat seams to avoid irritation during training.

3. T-Shirts

For beginners, wearing a cotton or athletic T-shirt under the gi is common.

Benefits:

• Affordable: A simple and cost-effective option.
• Accessible: Most people already have T-shirts they can use.

Drawbacks:

• Cotton retains moisture, making it less comfortable during long sessions.
• T-shirts can bunch up and become a distraction.

Pro Tip:

• If you choose a T-shirt, opt for one made from moisture-wicking materials.

4. Sports Bras (For Women)

For female practitioners, a well-fitting sports bra is essential.

Benefits:

• Provides support and ensures comfort during training.
• Designed to minimize movement and prevent discomfort.

Pro Tip:

• Look for high-impact sports bras that can handle the physical demands of BJJ.

5. Cups and Groin Protectors (For Men)

Groin protectors aren’t mandatory in all academies. But they can offer extra protection.

Benefits:

• Shields sensitive areas from accidental strikes or pressure.
• Adds confidence during intense sparring.

Pro Tip:

• Ensure the cup fits comfortably and doesn’t restrict movement.

6. Nothing (Traditional Approach)

Some practitioners prefer not to wear anything under their gi.

Benefits:

• Maximum breathability and freedom of movement.
• Traditionalists argue it’s more in line with BJJ’s origins.

Drawbacks:

• Less hygienic due to direct contact with the gi and mats.
• Offers no protection against chafing or mat burns.

Pro Tip:

• If you choose this approach, ensure your gi is clean and fits well to avoid discomfort.

What Not to Wear Under Your BJJ Gi

• Loose Clothing: Baggy items can bunch up and restrict movement.
• Zippers or Buttons: These can damage your gi or scratch training partners.
• Heavy Fabrics: Avoid materials that retain moisture. As they can become uncomfortable and increase the risk of skin issues.

Additional Tips for Choosing What to Wear Under Your BJJ Gi

• Check Your Academy’s Rules: Some gyms have specific guidelines on what’s acceptable under the gi.
• Prioritize Hygiene: Always wash your gear, including anything worn under the gi, after every session.
• Invest in Quality Gear: High-quality rash guards and compression wear last longer. Thus provide better performance.
• Layer According to Weather: Adjust your layers based on the training environment.
