When I first started training Jiu-Jitsu, I didn’t think much about what I was wearing. I threw on an old under armor compression shirt, hit the mats, and focused on surviving each roll. But over time, I learned that what you wear actually matters—a lot. The right rash guard isn’t just about looking sharp; it can make a real difference in performance, durability, and protection. If you’re serious about Jiu-Jitsu, investing in a high-quality rash guard is one of the best moves you can make.
If you’ve ever bought a cheap rash guard, you probably know the disappointment of seeing it stretch out, fade, or fall apart after just a few months. The difference between a basic rash guard and a well-made, high-performance one comes down to materials and construction. A quality rash guard is designed to handle years of rolling, with reinforced stitching, high-quality fabric blends, and sublimated designs that won’t crack or peel. You shouldn’t have to replace your gear every few months—your rash guard should be built to last.
A rash guard isn’t just something you throw on for looks—it plays a real role in performance. If it’s too loose, it bunches up and gets in the way during scrambles. If it’s too tight, it’s uncomfortable and restrictive. A well-fitted rash guard moves with you, offering just the right amount of compression to help with circulation and recovery. The best ones are made with four-way stretch fabric, so they flex with every movement while also wicking sweat away from your skin.
One of the biggest reasons to wear a rash guard is hygiene. Jiu-Jitsu is an intense, full-contact sport, and that means a lot of time spent grappling on shared mats. Ringworm, staph, and other skin infections can spread fast in a gym setting, especially if you’re rolling in a sleeveless tank or an old cotton tee. A rash guard creates a protective barrier between your skin and the mats, reducing the risk of infections while also preventing mat burns and abrasions.
If you’ve ever trained in a regular T-shirt, you know how uncomfortable it gets—soaked in sweat, heavy, and sticking to your skin. A high-quality rash guard is designed to pull moisture away from your body, keeping you cool and dry, even during long training sessions. Whether you're grinding through rounds in a hot gym or hitting an open mat on a humid day, the right rash guard makes a difference.
Beyond function, a rash guard is also a way to express your identity. Whether it’s repping your gym, your personal brand, or a design that speaks to your style, wearing the right rash guard lets you stand out. That’s why at Asgard Supply Co., we create premium custom rash guards for gyms and teams, blending high-performance materials with clean, stylish designs that look as good as they feel.
Not all rash guards are made equal. If you’re looking for one that will hold up to years of training, here’s what to keep in mind: sublimated designs that won’t fade, reinforced stitching for durability, four-way stretch fabric for comfort, and moisture-wicking materials to keep you dry.
A high-quality rash guard isn’t just another piece of gear—it’s an investment in your performance, protection, and style. If you’re ready to upgrade your training gear, check out our latest rash guard collection HERE .
