Oni Rash Guard
There’s a difference between training… and imposing your will.
The Oni Rash Guard was built for the latter.
Designed as a high-performance rash guard for jiu-jitsu, this piece blends durability, comfort, and presence into something you’ll reach for every time you step on the mat. Whether you’re drilling, rolling, or competing, it stays locked in and holds up under pressure.
The Oni design pulls from traditional Japanese imagery—symbolizing strength, discipline, and controlled aggression. It’s bold without being loud, detailed without being overdone, and built to stand out without sacrificing function.
This isn’t a rash guard that looks good for a week and fades into the bottom of your gym bag. It’s made to take the daily grind—hard rounds, constant washing, and everything that comes with real jiu-jitsu training.
The compression fit moves with your body, not against it. It stays in place during scrambles, doesn’t bunch up mid-roll, and keeps you comfortable through long sessions. The material is breathable, sweat-wicking, and built to maintain its shape over time.
If you’re looking for a rash guard for jiu-jitsu that performs as well as it looks, this is it.
Built for battle. Styled for victory.
