The Complete Guide to BJJ Rash Guards: Protection, Performance & Custom Designs
Introduction
If you train Brazilian Jiu-Jitsu (BJJ), you’ve probably noticed that more and more athletes are rolling in rash guards. Whether you’re a beginner stepping onto the mats for the first time or a competitor preparing for no-gi tournaments, rash guards are more than just stylish gear — they’re essential for protection, hygiene, and performance.
In this guide, we’ll explain why rash guards are important, what to look for when buying one, and how custom rash guards can give you a personal edge.
1. What Makes a Rash Guard Essential in BJJ?
Unlike cotton t-shirts, rash guards are made from lightweight, stretchable materials that keep you safe and comfortable during training. Here’s why they’re a must-have:
-
🛡️ Skin Protection: Prevents painful mat burns and scratches.
-
🧼 Better Hygiene: Reduces exposure to bacteria and infections like ringworm.
-
⚡ Performance Boost: Compression fit helps blood circulation and recovery.
-
🥋 Competition Ready: IBJJF-approved rash guards let you compete in ranked divisions.
2. Key Features to Look For
When choosing a rash guard, don’t just grab the cheapest one you find. Pay attention to:
-
Fabric Quality: Look for polyester + spandex blends with 4-way stretch.
-
Durability: Flatlock or reinforced stitching prevents tearing.
-
Design Type: Fully sublimated graphics last longer and won’t crack.
-
Fit: Snug enough to prevent opponent grips, but not overly restrictive.
-
Rank Colors: White, blue, purple, brown, or black for IBJJF competition compliance.
3. Common Mistakes When Buying Rash Guards

❌ Picking oversized rash guards that opponents can grip.
