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

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.

Rashguard Care Tips

Treat your rashguard right and it’ll last years. Always:

✅ Wash cold after every roll
✅ Hang dry — never use heat
✅ 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.
