Are Rash Guards Worth It in BJJ? Absolutely! Here's Why

by Adrian Davis March 30, 2025

Rash guards are more than just a stylish piece of gear in Brazilian Jiu-Jitsu (BJJ) — they are an essential component for both comfort and performance. If you're on the fence about whether to invest in a rash guard for your training, here’s why they’re worth every penny.

1. Skin Protection:

BJJ is a high-contact sport, and skin-to-skin contact is unavoidable. Rash guards create a barrier between your skin and potential mat burns, cuts, and scrapes. They also reduce the risk of skin infections like ringworm, staph, and impetigo — common issues in grappling environments.

2. Sweat Management:

Rash guards are made from moisture-wicking materials like polyester and spandex, which help manage sweat and keep you dry during intense rolls. Unlike cotton shirts, they don't get heavy or sticky, preventing discomfort and chafing.

3. Muscle Compression:

The compressive fit of rash guards supports your muscles, promoting better blood circulation and reducing muscle fatigue. This can enhance performance, help with faster recovery, and reduce the risk of strains.

4. Improved Grip and Control:

In No-Gi BJJ, a smooth, fitted rash guard minimizes your opponent's ability to grip your clothing. It also helps maintain your grip and positioning without getting tangled in loose fabric.

5. Mat Etiquette and Hygiene:

Wearing a rash guard shows respect for your training partners by maintaining proper hygiene. It prevents excessive sweat transfer, making training more comfortable and sanitary for everyone.

6. Durability and Longevity:

Rash guards are built to withstand the rigors of grappling. High-quality rash guards are durable, resistant to tearing, and maintain their elasticity and color even after repeated washes.

7. Style and Self-Expression:

Many rash guards feature unique and stylish designs, allowing you to express your personality on the mats. Whether you prefer a classic look or a bold statement, there's a rash guard for every style.

Conclusion: Worth Every Penny!
Whether you're a beginner or a seasoned BJJ practitioner, investing in a quality rash guard is a smart choice. It not only enhances your performance but also protects your body and maintains hygiene. If you’re serious about your training, a rash guard is definitely worth it!
