Why Rashguards Are Essential for Hygiene in BJJ and MMA

Whether you're rolling in Brazilian Jiu-Jitsu or drilling in MMA, rashguards are more than just stylish training gear — they're an essential part of your hygiene strategy on the mats.

Unlike regular cotton t-shirts, rashguards are specifically designed to protect your skin, wick away sweat, and reduce the risk of skin infections like ringworm and staph. If you're serious about training — especially in no-gi — wearing a rashguard isn't optional.

What Is a Rashguard?

A rashguard is a close-fitting, stretchy top made from moisture-wicking synthetic fabrics like polyester or spandex. It’s built to protect your skin from friction, cuts, and bacteria during intense grappling sessions.

How Rashguards Help Maintain Hygiene

• Barrier Against Skin Infections: Mats can harbor bacteria and fungi. A quality rashguard acts as a protective layer between your skin and potential contaminants.
• Reduces Cuts and Scratches: Prevent mat burns and friction-based abrasions — which can lead to infections — by keeping your skin covered.
• Wicks Sweat: Rashguards pull moisture away from your skin, keeping you drier and helping prevent bacterial build-up.
• Easier to Wash and Dry: Rashguards dry faster than cotton shirts and don’t retain bacteria or odor the same way.

Why Cotton T-Shirts Aren’t Enough

While it may seem convenient to throw on a regular t-shirt, cotton traps sweat, stretches out, and tears easily. It also holds onto bacteria and becomes a hygiene hazard over time. Rashguards are built for the demands of martial arts training — they last longer and keep you safer.

Added Benefits Beyond Hygiene

• Compression Support: Some rashguards offer light compression, improving circulation and reducing muscle fatigue.
• Improved Grip for Partners: The slick surface helps prevent fingers from getting caught in loose clothing.
• Looks Professional: A good rashguard shows you're taking your training seriously — and respecting your training partners.

How to Care for Your Rashguard

• Wash in cold water after every session
• Avoid fabric softeners (they reduce moisture-wicking properties)
• Air dry to preserve elasticity and prevent shrinkage

Frequently Asked Questions

Are rashguards necessary for BJJ?

Yes. Rashguards are essential for BJJ, especially in no-gi training. They help protect your skin from mat burns, reduce the risk of infections like ringworm or staph, and improve hygiene during grappling sessions.

Can I wear a cotton t-shirt instead of a rashguard?

It’s not recommended. Cotton shirts retain sweat, stretch out, and are more likely to tear. They also trap bacteria and become unhygienic quickly. Rashguards are specifically designed for martial arts training and provide better skin protection and comfort.

Do rashguards help prevent skin infections?

Yes. A properly fitted rashguard creates a barrier between your skin and the mat, reducing the risk of skin-to-skin or mat-to-skin infections such as ringworm, impetigo, or staph.

How tight should a rashguard be?

Rashguards should fit snugly without restricting movement. A tight fit helps prevent it from bunching or riding up during training while also offering light compression and moisture control.

How do I wash and care for my rashguard?

Wash your rashguard in cold water after each use. Avoid bleach and fabric softeners. For best results, air dry it instead of using a dryer to maintain the stretch and moisture-wicking ability.
