Rashu – Your Specialized Rash Guard Store for BJJ and Grappling

Brazilian Jiu-Jitsu is a demanding discipline. A high-quality long-sleeve BJJ rash guard is more than just sportswear—it protects your skin, enhances performance, and provides essential comfort during fights and intense training sessions.

Our BJJ rash guards are designed for Jiu-Jitsu practitioners, but they’re also perfect for grappling, MMA, and boxing. Our products offer optimized compression, quick drying, and resistance to friction.

No worries—we’ll explain why wearing a rash guard is crucial in BJJ and why you can trust us for your training needs!

Why Wear a Rash Guard in Brazilian Jiu-Jitsu?

Protection Against Irritations and Friction

In BJJ and grappling, your skin goes through a lot. Tatami contact, arm locks, and repeated grips can cause irritations and friction burns.

A compression shirt specifically designed for BJJ acts as a second skin, reducing abrasions while also preventing excessive sweat buildup. Additionally, it protects against bacteria and common skin infections found in combat sports.

Performance Enhancement and Muscle Support

You’ve probably noticed that at Rashu, we stand out with unique, carefully designed rash guards that break the mold. However, our rash guards aren’t just about style—they’re designed to boost performance.

Thanks to their compressive fabric, they provide muscle support that reduces fatigue and optimizes recovery. Here’s what you need to keep in mind:

Optimized compression for better blood circulation and reduced soreness
Breathable fabric that wicks sweat away, keeping your body at an ideal temperature
Quick-drying properties—perfect for back-to-back grappling sessions without discomfort

If you choose a long-sleeve rash guard for BJJ, you can be sure to experience fluid movements without the inconvenience of a sticky or deformed t-shirt.

What Defines a High-Quality BJJ Rash Guard?

A technical rash guard for BJJ must meet several criteria to ensure comfort and durability. Here are the key elements to check before buying your gear:

Sleeve length: Opt for long sleeves to protect your skin from friction and keep your muscles warm
Compression level: Optimal compression enhances blood circulation and reduces muscle fatigue
Fabric quality: Choose a technical fabric like the ones we use at Rashu—lightweight, breathable, and stretchable for maximum comfort
Flat seams: Prevent irritations and increase durability
Quick-drying fabric: This is crucial—it helps you stay dry and avoids post-training chills

Our rash guards are built to withstand intense BJJ training without stretching out or losing elasticity after multiple washes. That means all the features above are guaranteed, with top-quality products!

A BJJ Rash Guard Adapted to Your Style and Discipline

Whether you train in Gi or No-Gi, a high-quality rash guard is essential to improve your endurance and resistance over the long term. Quality is key, but what would a rash guard be without a touch of personalization?

The classic black rash guard is often preferred for its simplicity, but our models offer a wide range of modern and aggressive designs, inspired by Brazilian Jiu-Jitsu, MMA, and grappling.

We provide minimalist patterns, but also bolder designs for those who want to showcase their identity on the tatami. In short, Rashu breaks the mold, allowing you to express your vision, your way!

All our models feature an ergonomic fit that adapts to all body types. However, be sure to check the size guide available on each product page to avoid any surprises!

Tips for Choosing the Right Compression Top

A good compression top for BJJ should be selected based on several key factors:

✔️ Choose a snug fit that hugs your body without excessive compression.
✔️ Check the quality of the seams, especially around the shoulders and underarms.
✔️ Opt for a breathable, stretch-resistant fabric, like the ones we offer at Rashu.
✔️ Look at the technical specifications: antibacterial protection, quick sweat evaporation, and durable fabric.

Proper Care to Keep Your Rash Guard in Top Condition

Taking proper care of your rash guard is essential if you want it to last through many BJJ training sessions!

To maximize the durability of your BJJ rash guard, follow these simple care rules:

✔️ Wash in cold water (86°F / 30°C max) to preserve fabric elasticity.
✔️ Avoid tumble drying, as it can affect compression and breathability.
✔️ Air dry in the shade to prevent UV damage.
✔️ Skip fabric softeners, as they can reduce the effectiveness of technical fabrics.

By following these tips, your rash guard will maintain its performance for longer!
