Your Custom Rash Guard Guide Starts Here
If you’ve thought about ordering a custom rash guard, you’ve probably run into the same questions: where do you order one, how does the process work, will it last, and how do you design something that doesn’t look terrible when worn? This guide answers all of those questions in one place.
Whether you’re designing a custom rash guard for yourself, your team, or your brand, you’ll understand exactly how the process works and how to get the best result. If you want to go straight to designing, open our 3D configurator and start building in real time.
What Is a Custom Rash Guard?
A custom rash guard is a performance shirt built for sports like Brazilian Jiu Jitsu, MMA, and surfing. It protects against friction, helps regulate moisture, and provides a tight, flexible fit for movement.
A custom rash guard takes that one step further. Instead of buying a generic design, you create your own — your colours, your logo, your design. It becomes both performance gear and a visual identity. According to IBJJF, team identity in no-gi competition has grown significantly, with academies increasingly using custom kits to represent their school.
Why Athletes Choose a Custom Rash Guard
Most people don’t start with design. They start with a problem. They want a custom rash guard that represents their team, looks unique, and actually lasts through training.
Durability is one of the biggest concerns in combat sports communities. Cheap rash guards go thin quickly, while well-made ones last years. That’s why ordering a custom rash guard isn’t just about aesthetics — it’s about control over quality and performance from the start.
How a Custom Rash Guard Is Made
The process is simpler than most people expect. It usually starts with an idea — a logo, a colour scheme, or just a rough concept. From there, the design is created digitally and adapted to fit the shape of the garment.
Once finalised, the design is printed onto the fabric using sublimation — the industry standard for performance sportswear. After printing, the fabric is cut, sewn, and assembled into the final product. Modern production combines design, printing, and stitching into a precise workflow that ensures consistency and durability across every piece in an order.
The Most Important Decision for Your Custom Rash Guard
This is where most people make mistakes. There are different ways to print on sportswear, but for rash guards, one method clearly stands out.
✅ Sublimation — the Custom Rash Guard standard
- Ink bonds permanently inside fabric fibers
- No cracking, peeling or fading under stretch
- Full breathability — no surface layer
- Unlimited colours and all-over coverage
- Lasts as long as the garment itself
⚠️ Traditional Printing
- Ink sits on top of the fabric surface
- Cracks along stretch lines with use
- Reduces breathability of the garment
- Limited colours per design
- Fades and peels in high-friction sports

What Makes a High-Quality Custom Rash Guard
Printing is only part of the equation. The material and construction matter just as much.
Most high-quality rash guards use a blend of polyester and spandex. Polyester provides durability and moisture control, while spandex allows stretch and mobility.
Beyond fabric, flat seams eliminate irritation during training. Compression fit improves performance and recovery. And breathable construction keeps you regulated through long sessions. When all of these elements come together, the result is a shirt that feels like a second skin during training.
How to Design a Custom Rash Guard That Looks Good
This is one of the biggest hidden challenges. Designs that look great on a screen can look completely different when worn. A few key principles make a big difference.
Start simple. Overly complex designs often distort on stretchy fabric. Think about movement — areas like the chest and shoulders stretch the most, so placing key elements there requires care. Use strong contrasts. Sublimation keeps colours vibrant, so bold designs work best.
And most importantly, design for the whole garment. Rash guards are not like t-shirts. They are 360-degree canvases. Our 3D configurator lets you see the full design from every angle before committing to anything.
Common Mistakes to Avoid
One of the biggest mistakes is choosing the wrong fabric. If the material doesn’t support performance, even the best design won’t matter. Another is ignoring how fabric stretches — designs can warp if not adapted to the body shape. Low-resolution artwork is a third common issue, resulting in blurry prints instead of sharp graphics. These small details have a big impact on the final result. Read more about rash guard construction standards at Grappling Insider.
What Are Custom Rash Guards Used For?
Custom rash guards are used across multiple sports and environments. In BJJ and MMA, they reduce friction, improve hygiene, and provide compression. In surfing and water sports, they protect against UV exposure and abrasion while remaining lightweight and quick-drying. According to BJJ Heroes, team identity through custom gear has become central to how academies present themselves in competition.
They are also widely used for team uniforms, club branding, and personal identity — making them one of the most versatile pieces of sports apparel available.
The Easiest Way to Order a Custom Rash Guard

Custom Rash Guard FAQ
How long does a custom rash guard last?
A well-made sublimation rash guard is built to last more than 5 years of regular training. Because the ink is embedded inside the fabric fibers, the design doesn’t fade, crack, or peel. The fabric or stitching typically reaches end of life before the print does.
What is the minimum order for a custom rash guard?
Our minimum order quantity is 40 pieces per design. This applies to all shirt types — BJJ rash guards, surf shirts, and paddle tops. All orders include free worldwide shipping.
What fabric is used for a custom rash guard?
We use high-performance polyester and spandex blends selected for four-way stretch, breathability, moisture-wicking, and sublimation compatibility. BJJ and MMA rash guards are optimised for grappling use, while water sports shirts prioritise UV protection and quick-dry properties.
Can I design my own custom rash guard?
Yes — completely. Our 3D configurator gives you full control over colours, logos, and layout without any design software. You see the result in real time and can adjust freely before placing your order.
How much does a custom rash guard cost?
Our shirts start from €19.90 per piece. Pricing depends on quantity and shirt type. All orders of 40 pieces or more include free worldwide shipping. The key difference from retail is that you are paying for personalisation and production — not just the garment.
