If you're new to Brazilian Jiu-Jitsu, you’ve probably seen people training in both rashguards and compression shirts — and maybe you’ve even wondered: aren’t they the same thing?
Not quite. Let’s break down the key differences so you know exactly what to wear when you hit the mats.
What Is a BJJ Rashguard?
A rashguard is a compression-fit shirt designed specifically for grappling sports like Brazilian Jiu-Jitsu. It’s engineered to hold up under high-stress movements, sweaty rolls, and intense friction.
✅ Durable flatlock stitching
✅ Anti-microbial material
✅ Long or short sleeve options
✅ Reinforced design to prevent ride-up
✅ IBJJF legal designs for no-gi competition
What Is a Regular Compression Shirt?
Compression shirts — like the kind used for running or lifting — are built for sweat management and muscle support, but they’re not made for grappling. That’s where things start to fall short for BJJ.
❌ Often thinner and prone to tearing
❌ Loose or itchy seams
❌ No waistband to prevent ride-up
❌ Not always safe for rolling
Key Differences: Rashguard vs Compression Shirt
| Feature | BJJ Rashguard | Compression Shirt |
|---|---|---|
| Designed for grappling | ✅ Yes | ❌ No |
| Reinforced stitching | ✅ Yes | ❌ Rarely |
| Anti-slip waistband | ✅ Often | ❌ No |
| IBJJF legal | ✅ Yes | ❌ No |
| Long-term durability | ✅ Built to last | ❌ Prone to tearing |
Why Does It Matter?
If you’re rolling, you want a shirt that:
-
Stays in place
-
Doesn’t rip under pressure
-
Keeps you safe from mat burn and skin infections
-
Meets gym and tournament rules
A rashguard does all that. A compression shirt? Not so much.

✅ Turn inside out before washing
✅ Avoid bleach or fabric softener
Final Thoughts
While compression shirts might seem like a cheap shortcut, they don’t hold up in BJJ. A proper rashguard protects your skin, holds its shape, and keeps you rolling in comfort — from your first class to your first tournament.
