    The No-Gi Option: Rash Guards

    First up, rash guards. They're the unsung heroes of the BJJ world, often overshadowed by the more visible gi. Rash guards are snug-fitting shirts made from materials like spandex, nylon, or polyester, designed to protect your skin and muscles.

    Rash guards wick away sweat, reducing the chance of skin infections. They also shield your skin from the mat, helping you avoid the dreaded "mat burn." It's a win-win!

    But there's more to rash guards than just protection. They can also enhance your performance by improving blood circulation and muscle recovery. This is due to their compression properties, which offer added support to your muscles during intense bouts.

    Rash guards come in two varieties: short sleeves and long sleeves. If you're grappling in a cooler environment, a long-sleeved rash guard might be your best bet. It's warmer, and it offers more protection. On the flip side, a short-sleeved rash guard is cooler and could be a better option for training in warmer weather.

    • Pros: Protective, sweat-wicking, flexible, and muscle supportive.
    • Cons: Can be tight, might restrict breathing if not sized properly, may not be as durable as desired.

    Another Option: Compression Shorts/Spats

    Moving down, let's talk about compression shorts or spats. These are the lower body's answer to rash guards. They provide the same benefits: protection, sweat-wicking, muscle support, and improved performance. In short, they're rash guards for your legs.

    Compression shorts/spats help protect your thighs from mat burn and reduce the risk of muscle strains. They're great for those who prefer a snug fit and don't mind showing off their leg muscles!

    And just like rash guards, compression shorts come in different lengths. You can choose from short, mid-length, or full-length spats, depending on your comfort and the level of protection you want. It's all about finding the right balance for your needs.

    But remember, while they offer many benefits, they're not for everyone. Some people find them too restrictive or uncomfortable. And if they're not sized correctly, they can hamper your movement, which is the last thing you want in a BJJ match.

    The Traditional Way: Jiu-Jitsu Underwear

    But let's not forget the traditional Jiu-Jitsu underwear. These are the standard undergarments for BJJ practitioners. Unlike everyday underwear, they're designed specifically for the demands of BJJ, ensuring the right balance of comfort and functionality.

    Jiu-Jitsu underwear comes in various styles, from briefs and boxers to compression shorts. They offer less protection compared to rash guards and spats but are generally more comfortable for many practitioners. After all, there's a reason they're the traditional choice.

    When it comes to materials, most Jiu-Jitsu underwear is made from breathable fabrics like cotton or bamboo. These materials help wick away sweat and keep you comfortable during intense training sessions. Some also include a touch of elastane or spandex for added flexibility.

    But, as with any gear, not all Jiu-Jitsu underwear is created equal. Some offer better quality and durability than others. And while they might be more comfortable, they often lack the protective qualities of rash guards and spats. It's a trade-off you need to consider.

    • Pros: Comfortable, designed specifically for BJJ, wide variety of styles.
    • Cons: Can lack the protective qualities of rash guards and spats, might not be as durable, requires careful selection for quality.

    Going Commando: Not Recommended

    Some practitioners consider going commando under their gi. It's the ultimate expression of freedom, with no restrictions whatsoever. But, it's a risky move, and it's not generally accepted in the BJJ community.

    Going commando may give you a sense of freedom, but it comes with significant downsides. The lack of protection can lead to hygiene issues and skin irritation. Plus, it's a safety risk, as sudden movements could lead to wardrobe malfunctions. It's not worth the risk, folks.

    Moreover, going commando can be frowned upon by other practitioners. BJJ is a close-contact sport, and personal hygiene is paramount. Wearing appropriate undergarments is a sign of respect toward your training partners. It's part of the BJJ etiquette. In short, going commando under your gi is not recommended. It's better to stick to one of the other options we've discussed. Trust us, your training partners will thank you!

    • Pros: Complete freedom, no restrictions.
    • Cons: Risks hygiene issues, lacks protection, frowned upon in the BJJ community.

    Additional Considerations: Choosing the Right Size and Material

    Also, no matter what option you go for, it's crucial to choose the right size and material. Too tight, and it could restrict your movement and breathing. Too loose, and it won't offer the protection and support you need.

    Finding the right size involves more than just looking at a size chart. It's about understanding your body and how it moves during a BJJ match. Always try on different sizes and styles before making a decision. And when in doubt, ask a more experienced practitioner or a coach for advice.

    As for material, it's all about comfort and functionality. Rash guards and spats are usually made from synthetic materials like nylon or polyester, which are great for sweat-wicking and durability. On the other hand, traditional Jiu-Jitsu underwear is typically made from more natural fabrics like cotton or bamboo, which are praised for their breathability and softness.

    But there's a trade-off. Synthetic materials might not be as comfortable as natural ones, but they often offer better performance features, like sweat-wicking and durability. On the other hand, natural fabrics are generally more comfortable but might not perform as well under intense physical activity.

    It's a matter of personal preference and what you value most in your gear. Do you prioritize comfort or performance? The answer to that question will guide your choice.

    • Pros: Right size and material can enhance comfort and performance.
    • Cons: Wrong size can restrict movement, and unsuitable material might not provide the desired comfort or functionality.

    Wrapping Up: Choose What Works for You

    So, you've got a lot of options for what to wear under your BJJ gi. Rash guards, spats, traditional Jiu-Jitsu underwear, or even going commando (though we don't recommend it). Each option comes with its own set of pros and cons, and there's no one-size-fits-all answer.

    Ultimately, the best choice depends on you. It's about your comfort, your performance, and your respect for the sport and your training partners. It's about finding the right balance for your unique needs.

    Try different options. Experiment with different styles, sizes, and materials. Listen to your body and how it responds to each option. And most importantly, enjoy the process. Because at the end of the day, BJJ is about more than just what you wear. It's about the experience, the challenge, and the joy of the sport.

    Now, with this guide in your hand, you're ready to make an informed decision. So go ahead, choose your gear, and get ready to roll. See you on the mat!
