What is a Rash Guard in Jiu Jitsu?

Before looking into the benefits of wearing a rash guard, let's first understand their role and why they're a staple in the BJJ gear bag.


A rash guard in Jiu-Jitsu is like a superhero suit for grapplers!


It's a form-fitting shirt, often made from stretchy, moisture-wicking material, designed to protect your skin from mat burns, reduce the spread of bacteria, and improve your overall comfort during those intense training sessions.

Benefits of wearing Rash Guards in BJJ

1. Skin Protection and Reducing Abrasions

When you're rolling on the mat, skin protection cannot be overstated. Rash guards provide a robust barrier between your skin and the mat, significantly reducing the risk of abrasions and cuts.


Skin abrasions and conditions like 'mat burn' are common among Jiu-Jitsu athletes, primarily due to the friction encountered during grappling.


Rash guards offer an effective solution by serving as a protective layer that minimises this friction, thereby reducing the incidence of skin injuries. 

Note: Always choose rash guards made with antimicrobial fabric to enhance hygiene further.

2. Hygiene

The barrier a rash guard has is crucial not only for your safety but also for maintaining hygiene.


The mats you train on are shared spaces, and despite regular cleaning, they can harbour bacteria and fungi.


A quality rash guard for combat sports can help shield you from potential skin infections, making it an indispensable part of your gear.

Remember: Regularly washing your BJJ rash guard is key to maintaining top hygiene. Also, be sure to follow the care instructions precisely for the best results.

3. Comfort and Mobility

For anyone practicing no gi jiu jitsu, comfort and mobility are paramount as your well aware.


Yes, rash guards are designed to fit snugly, ensuring they don't get caught or bunched up during close-contact drills or sparring.


This snug fit, combined with stretchable materials, allows for unparalleled freedom of movement, letting you execute techniques without restriction.

4. Muscle Support and Recovery

One often overlooked aspect of rash guards is their ability to provide muscle compression. This compression is not just about making you look more fit; it has tangible benefits for your performance and recovery.


By applying gentle pressure to your muscles, rash guards can improve blood circulation, which in turn helps in reducing muscle soreness and fatigue. 


This support is invaluable during long training sessions or competitions, where every bit of energy counts.


5. Thermal Regulation

Muscle compression also aids in thermal regulation, keeping your body temperature stable. Whether you're training in a chilly dojo or competing under the bright lights of a tournament, a rash guard helps maintain your body's optimal performance temperature.

Materials Used in Rash Guards

The effectiveness of a rash guard largely depends on its material. You're looking for a blend that offers durability, flexibility, and moisture management.


Polyester and spandex mixtures hit this sweet spot, providing a stretchable fabric that moves with you while resisting the wear and tear of grappling. Fabrics with antimicrobial properties are a bonus, helping keep your gear fresher for longer.

Different Types of Rash Guards

For rashguards there's a style for every grappler's preference and need.


From the short sleeve versions that offer freedom and flexibility, to the full coverage of long sleeves that protect against mat burns and keep you a bit warmer during cooler training sessions.


But the variety doesn't stop there!


You can also find rash guards with varying levels of compression to support muscle recovery, tank tops for those who want minimal restriction, and even rash guards with built-in UV protection for outdoor training. Each type has its own set of benefits, whether you're looking for maximum mobility, full protection, or something in between.


Tip: The choice between long and short sleeves may come down to personal preference or the specific conditions of your training environment.

Conclusion

The benefits of wearing rash guards in Jiu-Jitsu cover a wide range, from enhancing protection against skin infections and abrasions to improving muscle performance and recovery.


When selecting your next rash guard, consider factors like material quality, fit, sleeve length, and design to find the perfect match for your needs and preferences. With the right rash guard, you can step onto the mat with confidence, knowing you're fully equipped to train effectively, safely, and in style.
