Quick answer: A rash guard is a tight, durable shirt that protects skin from mat burn, friction and sun in BJJ, MMA and surfing; a compression shirt is built to support muscles during training. They look similar, but rash guards use tougher, often sublimated fabric and flatlock seams for grappling.
Brands launching fightwear or gym wear often ask whether they need rash guards, compression shirts or both. This guide explains the differences, the fabrics and construction that matter, and how to manufacture them under your own label.
Quick answer
For BJJ, MMA and grappling, make rash guards in about 200–240 GSM polyester-spandex with flatlock seams, a raised waist band or silicone gripper and full sublimation. For gym and running, make compression shirts in lighter, higher-compression nylon-spandex. For surf and swim, use rash guards with UPF 50+ sun protection.

Rash guard vs compression shirt
| Feature | Rash guard | Compression shirt |
|---|---|---|
| Main purpose | Protect skin from friction, mat burn, infection and sun | Support muscles, reduce vibration, wick sweat |
| Fabric | Polyester-spandex, about 200–240 GSM, very durable | Nylon-spandex or polyester-spandex, often lighter with higher compression |
| Seams | Flatlock, reinforced for grappling | Flatlock for comfort |
| Design | Usually fully sublimated with bold graphics | Plainer, often solid colours |
| Used for | BJJ no-gi, MMA, wrestling, surfing | Gym, running, team sports base layer |
Construction that matters for grappling
- Flatlock seams that lie flat and don’t rub or split
- Reinforced underarm and shoulder seams
- Elastic or silicone waist gripper so the shirt stays tucked in
- Sublimated graphics that never crack, even after many washes
- Anti-odour and quick-dry fabric treatments on request
Competition rules for BJJ
Many IBJJF no-gi events limit rash guard colours and graphics, for example requiring a minimum amount of black, white or the athlete’s belt colour. If you sell to competitors, offer a “ranked” range that follows the current IBJJF uniform rules, alongside freer training designs.
Long sleeve vs short sleeve
Long-sleeve rash guards give the most protection from mat burn and are popular for BJJ; short sleeves are cooler for MMA training and summer. Most brands offer both in the same design.
Building a fightwear range
Rash guards sell best alongside matching MMA shorts, spats and no-gi sets. See our guide on how to start a fightwear brand.

FAQs
Can I wear a compression shirt for BJJ?
You can for training, but a rash guard is tougher, has reinforced flatlock seams and stays tucked in, so it lasts longer on the mats.
What fabric are rash guards made of?
Usually polyester-spandex around 200–240 GSM, which stretches, dries fast and takes sublimation printing well.
Are rash guards good for surfing?
Yes. Surf rash guards protect from board rash and sun; ask for UPF 50+ fabric.
What is the MOQ for custom rash guards?
30 pieces per design at Ravix Pro, with mixed sizes and full sublimation.
Do you make IBJJF-compliant rank rash guards?
Yes. We can design rank colour ranges to follow the current IBJJF no-gi uniform rules.
