If you practice jiu-jitsu, MMA, or another combat sport, you’ve probably heard of a rashguard. But what exactly is it, and why do so many fighters refuse to start training without one?
A rashguard is a specialized garment originally designed for surfers but quickly gained popularity in combat sports such as BJJ, MMA, and grappling. It is characterized by its tight fit, compression effect, and durable material that protects the skin from abrasions, infections, and friction during close contact. The rashguard has now become an essential part of the gear for any serious jiu-jitsu practitioner.
What are the main advantages of a rashguard?
First and foremost, the rashguard protects the skin from scrapes, burns, and infections such as staph, which are common in contact sports. In grappling, where the body often comes into direct contact with the partner and the mat, this is crucial.
Second, rashguards are designed to provide maximum comfort during movement. They don’t bunch up, shift, or restrict motion — even during the most complex techniques in jiu-jitsu.
Another important benefit is body temperature regulation. Even though they fit snugly, rashguards are usually made from moisture-wicking materials that help cool the body and keep it dry even during the most intense workouts.
And last but not least – the style. Today, the market offers an endless variety of designs that can accurately express your personality, team affiliation, or cultural respect. You can pair a rashguard with matching shorts or a gi to create a complete set that not only functions well but also looks professional and stylish whenever you wear it.
The benefits of compression gear in training
Compression gear – like the rashguard – isn’t just a fashion trend. It provides real physiological benefits, especially during intense physical activity like BJJ, MMA, sparring, or conditioning.
One of the most important benefits is improved blood circulation. Compression promotes faster blood flow, leading to better oxygen supply to the muscles. This helps reduce muscle fatigue, especially during long and exhausting jiu-jitsu or grappling sessions.
In addition, compression clothing aids in recovery after exertion by accelerating the removal of lactic acid and reducing inflammation in the muscles. This means you’re much more likely to be fresh and ready for your next session when wearing a rashguard.
Some studies even show that compression wear can enhance performance during high-intensity exercises by improving muscle proprioception and promoting better posture, spatial awareness, and responsiveness while active on the mat.
What to look for when choosing a rashguard?
When selecting a rashguard, it’s not just about how it looks — although design plays a key role in confidence and identity, which everyone needs to bring out their best. Here’s what you should consider to ensure you’ve made a well-thought-out choice:
• Material: Look for a rashguard made from a high-quality polyester blend with spandex or elastane — this ensures durability, compression, and elasticity. This type of fabric is used by top-level fighters worldwide, and for good reason.
• Fit: Choose a model that fits snugly to your body but isn’t too tight. Seamless or flatlock seams are preferred to avoid irritation while ensuring maximum comfort and freedom of movement.
• Sleeves: Rashguards come in short-sleeve and long-sleeve versions. The former is better suited for those who prefer a lighter feel and more freedom on the mat, while the latter provides better protection against open wounds and skin infections during training.
• Shorts compatibility: If you train No-Gi, you’ll often want a rashguard set that includes matching shorts. This way, you combine functionality with aesthetics.
In conclusion
If you're serious about your development in jiu-jitsu, MMA, or another combat sport, a rashguard isn’t just an accessory — it’s a fundamental part of your gear that deserves your full attention. Of course, your skills and the effort you put into every training session will matter far more for your progress, but why compromise on comfort and appearance? A rashguard provides protection, comfort, faster recovery, and confidence. And the right design can be a reflection of your fighting spirit, your identity, and your vision.
Choose your rashguard now and feel the difference in your next training session!
