Rash guards are one of the best-selling products for martial arts gyms and fight brands. Every BJJ, MMA and no-gi athlete needs several, they are worn in every session, and a strong design builds loyalty to a gym or label. This guide explains how to order custom rash guards that perform on the mats and sell well in your shop.
What Does a Rash Guard Do?
A rash guard is a tight, stretchy top that protects the skin from mat burn and friction, reduces the chance of skin infections from the mat, and wicks sweat away from the body. In no-gi grappling it also gives a cleaner, less grippable surface than a loose T-shirt.
Fabric Choices
Polyester-spandex
The most common choice for custom rash guards. It stretches in four directions, recovers its shape, dries quickly and is ideal for full sublimation, so designs stay bright and will not crack.
Nylon-spandex
Smoother and slightly stronger, with a premium feel. It suits solid-colour rash guards or designs that use screen printing or heat transfer instead of sublimation.
Fabric weight and compression
Heavier fabrics give more compression and durability; lighter fabrics feel cooler. Ask your manufacturer for swatches so you can feel the difference before sampling.
Sleeve Lengths and Fits
- Long sleeve – full arm protection, the most popular for BJJ and no-gi.
- Short sleeve – cooler, popular for MMA and striking classes.
- Sleeveless – sometimes used for training and conditioning.
- Women’s cut – shaped through the waist and chest for a better fit.
Ranked Rash Guards
Many gyms sell ranked rash guards with colours that match belt levels: white, blue, purple, brown and black. Competitors in some federations, such as the IBJJF, may need ranked rash guards that meet specific colour rules for no-gi events. Check the current rules of the federation your athletes compete in before you design a competition range.
Construction That Lasts
- Flatlock seams lie flat and prevent chafing during rolling.
- Silicone waist gripper stops the rash guard riding up.
- Reinforced stitching at the underarms and shoulders, where grappling puts the most stress.
- Raglan sleeves for freer shoulder movement.
Design Tips
Full sublimation allows unlimited colours, all-over patterns and detailed artwork at no extra cost per colour. Because rash guards stretch, place important logos on the chest, upper back and sleeves, where the stretch is lower. Make sure your design files are high-resolution or vector so details stay sharp. Learn more in our printing methods guide.
Matching Fight Shorts and Spats
Rash guards sell best as part of a set. Matching MMA shorts and spats give your customers a full no-gi kit and increase the value of each order. Our MMA shorts guide covers fabric and fit for shorts.
Launching a Rash Guard Line
For gyms and fight brands, rash guards are an ideal first product: one design can be sold in several sizes and colourways. A B2B manufacturer can add your woven neck labels, hang tags and branded packaging so your product is ready for retail. See our private label service.
Sizing
Rash guards should fit tightly, so accurate sizing is important. Provide a size chart with chest, waist and length measurements, and consider ordering a size-run sample before bulk production.
Minimum Order
Custom rash guards from Naxon Sports start from 30 pieces per design, with sizes mixed, which makes it practical for a single gym to launch its own range.
