Men's BJJ Rash Guards & No-Gi Gear

38 products

Kingz rash guards are made for no-gi Brazilian jiu-jitsu (BJJ): a snug polyester and spandex fit that stays put through scrambles, with fully sublimated graphics that won't crack or peel. Choose short or long sleeve, everyday training designs or the Ranked Performance range in IBJJF rank colours, then complete the kit with grappling shorts and spats.

Why wear a rash guard for BJJ?

A rash guard protects your skin from mat burn, keeps sweat off your training partners and the mats, and stops a loose T-shirt from riding up or giving your opponent something to hold. Many academies require one for no-gi classes.

Is a rash guard just a compression shirt?

They look similar, but a BJJ rash guard is built for grappling: a performance cut for a full range of movement, durable stretch fabric and graphics sublimated into the fabric rather than printed on top, so they survive constant friction and washing.

Short sleeve or long sleeve?

Short sleeve is cooler and the most popular choice for everyday training. Long sleeve covers more skin, which helps against mat burn and keeps you warmer in a cold academy. Our Ranked Performance V2 long sleeve adds a mesh panel under the arm for ventilation.

Rash guards for IBJJF no-gi

IBJJF no-gi events require a rash guard that shows your belt rank colour. The Ranked Performance range is made in IBJJF-approved rank colours.

Frequently Asked Questions

Do I need a rash guard for no-gi BJJ?
Many academies require one. A rash guard protects your skin from mat burn, keeps sweat off your partners and the mats, and won't ride up or give your opponent a grip the way a T-shirt can.

What size rash guard should I get?
Kingz rash guards are a snug athletic fit: XS 45–54 kg, S 54–66 kg, M 66–77 kg, L 77–91 kg, XL 91–102 kg, XXL 102–118 kg. Size up if you prefer a looser fit.

Can I wear any rash guard at IBJJF no-gi events?
IBJJF no-gi events require a rash guard that shows your belt rank colour. Our Ranked Performance rash guards are made in IBJJF-approved rank colours.

How should I wash a rash guard?
Wash after every session, inside out on a cold cycle, and hang dry. Avoid the tumble dryer and fabric softener, which wear down stretch fabric and graphics faster.
