BJJ Rash Guards and Shirts

Jiu Jitsu shirts and rash guards

Everyone will know just how seriously you take Jiu Jitsu when you express yourself with these one-of-a-kind designs.

Support your local BJJ gym!

If you are anything like me, your gym’s coach has been there for you in more ways you can count. 

Our local BJJ gyms have been there for us, now it is my turn to be there for them. A percentage of what I make on each shirt will go back to the local Jiu Jitsu community. 

If you want to help and can’t afford to buy a shirt, a share can be helpful too. The more people see this the more I can give back. 

Thanks! Ooss! 

Who is Jest.Ninja?

Hi! I’m Timothy Eberly. I am a  designer and illustrator. I grew up with a can of spray paint in my hands. I have been creating graffiti pieces for years and am now putting these works on Jiu Jitsu rash guards and shirts.

It takes a certain breed of individual to repeatedly get tapped out and come back asking for more.

I want people like you have the freedom to express yourself. 


"I love it. It fits great. I’m 6’1” 210 lbs and ordered a large. I’d say it’s pretty much perfect size. Not too tight, not too loose, and it’s long enough to tuck it into my shorts and it won’t come untucked. The material is nice and comfortable. And the monkey design is awesome. Great product man!"
