Explore our full lineup of World Cup Rash Guards, designed for no-gi athletes who demand durability, performance, and clean professional style. Each rash guard features competition-ready materials and minimalist designs suitable for training, open mats, and tournaments.
We want grapplers to understand what they’re buying — and what they’re not. We’re confident in our gear, which is why we’re clear about what it cannot do.
Our rash guards won’t make you better at Jiu-Jitsu, and we don’t spend heavily on hype or athlete marketing. We invest in materials, fit, and construction, not promises.
We’re also not the cheapest option. We’re a small, family-run brand focused on quality at a fair price, not cutting corners.
What we build is simple: durable gear, consistent fit, and designs made for real training — without exaggerated claims.
A great BJJ rash guard should disappear once training starts — no bunching, no restriction, and no distractions. The right fit delivers consistent compression while allowing full range of motion for scrambles, guard work, and transitions.
Fabric performance matters. Moisture-wicking materials manage sweat, dry quickly between rounds, and help reduce odor and skin irritation. For a deeper breakdown of long-term performance and construction, see our guide on what makes a durable BJJ rash guard.
Construction is just as important as fabric. Flatlock stitching reinforces high-stress areas while minimizing irritation, and an anti-slip waist lining helps keep the rash guard in place during training.
A quality BJJ rash guard isn’t just about how it looks — it’s about durability, comfort, and reliability on the mats.
Both short sleeve and long sleeve BJJ rash guards serve a purpose — the right choice depends on how and where you train.
Short sleeve rash guards are popular for no-gi training due to increased mobility and airflow, staying cooler during intense rounds and high-pace sessions.
Long sleeve rash guards offer more skin coverage, helping reduce mat burn, scratches, and friction, with some athletes preferring them for grip management and added protection during extended training.
Many grapplers keep both options in rotation, choosing based on training intensity, personal comfort, and gym environment. For a detailed breakdown, see our guide on short sleeve vs long sleeve BJJ rash guards.

Choosing the right BJJ rash guard comes down to fit, durability, design, and how different brands prioritize those details. If you’re comparing Nation Athletic to other popular rash guard brands, we’ve put together a set of honest, side-by-side guides to help you decide what matters most for your training.
FAQ
A good BJJ rash guard should be durable, moisture-wicking, and designed to stay in place during hard training. Reinforced flatlock stitching and high-stretch fabric are essential for no-gi jiu jitsu, helping the rash guard hold up under pressure while allowing full mobility.
Yes. Nation Athletic BJJ rash guards are built for athletes who train 4–6 days per week and are designed to withstand repeated washing, intense rolling, and competition prep. They’re constructed using reinforced stitching and premium fabrics chosen to handle daily use and the physical demands of hard rounds. Our focus is long-term durability, so grapplers who train multiple times per week can rely on their gear holding up over time.
Absolutely. These rash guards are designed for no-gi BJJ but also work well for MMA, wrestling, and cross-training thanks to their compression fit, mobility, and abrasion resistance.
No. Nation Athletic rash guards are cut specifically for grappling and designed to stay in place during scrambles, guard work, and live rounds without bunching or riding up.
Many Nation Athletic rash guards are suitable for competition, but athletes should always check specific event rules regarding colors, branding, and uniform requirements before competing.
To extend the life of your BJJ rash guards, wash them cold immediately after training and hang dry when possible. Avoid high heat and fabric softeners to protect performance fabrics and stitching.
A BJJ rash guard should fit snug without restricting movement. Excess fabric can snag on smaller joints and cause discomfort, while a proper compression fit helps prevent the rash guard from riding up during training. This allows full mobility for guard play, scrambles, and transitions.
Rash guard sizing is typically determined by height and weight. If you are between sizes, we recommend sizing up, as compression fabric will still remain form-fitting. If you’re unsure, refer to our rash guard size guide to find the best fit for your build.
For no-gi jiu jitsu, rash guards are typically paired with grappling shorts or spats for full coverage and comfort. Many athletes match their rash guard with no-gi shorts for competition-ready mobility and a secure fit during scrambles and guard work. Our range of grappling shorts include velcro and non velcro closures.
Yes. Nation Athletic rash guards are designed to work equally well for beginners and experienced grapplers. Beginners often put more stress on gear due to less controlled movement, which makes durability especially important early on. At the same time, our rash guards are tested by high-level competitors to ensure they perform under intense training and competition conditions. This makes them a reliable choice at any stage of your jiu-jitsu journey.
Nation Athletic rash guards are designed for grapplers who train regularly and expect their gear to last. Instead of cutting costs on materials or construction, we focus on durability, functional design, and long-term wear. Our rash guards are tested by experienced grapplers, built with reinforced stitching, and made using premium fabrics chosen for both performance and longevity. We prioritize clean, modern designs over gimmicks, and we stand behind every piece with a quality guarantee.
Nation Athletic was founded by grapplers for grapplers. The brand was built by someone who trains, understands the demands of jiu-jitsu, and experienced firsthand how often gear fails under real use. From the beginning, the focus has been on supporting everyday athletes — people balancing work, family, and training — rather than relying on hype or manufactured influencer marketing. Every product reflects that practical, training-first mindset.
