Fit Reference
Straight From The Mats
Real grapplers, real rounds, real gear that survives them.
Trusted On The Mats
Real reviews from real grapplers who train in Rotten BJJ.
Nice fit, sizing is great and cool design
Bought the Gugu Gaga as a joke for the boys and now everyone wants one lol.
Showed up in the tuxedo print looking like I'm about to host the Oscars. Coach lost it. Compression is on point.
Bought the Frankenstein for our Halloween in house and ended up wearing it every week. Holds up to the nastiest gas-tank rounds.
John wick is fire, definitely buying again
I got so many compliments 😆 amazing design!
Copped the Santa set for December rounds and now I'm 'Santa' at the gym forever. Super comfy and the print hasn't faded.
The detail on the back is sick, and it fits perfect.
Wore the hairy-chest one to class and my coach genuinely thought I forgot my rashguard. Funniest money I've spent on gear.
Tapped three blue belts in the Princess of Submissions and the disrespect was worth every penny. Wish the pink was a touch darker, but the fit is perfect.
Fav rashguard for sure fits crazy good, will buy gugu gaga next 😂
Nah this rashguard is crazy work , I'm wearing this all day
The Rotten Promise
Gear That Earns Its Spot
Loud designs are easy. Building rashguards that survive years of hard rolling is the hard part. We do both — here's what every Rotten BJJ set promises you.
Built To Survive Every Roll
Heavyweight four-way-stretch fabric and flatlock seams engineered for the nastiest scrambles. This isn't fast fashion — it's mat armor.
Prints That Never Quit
Every design is sublimated into the fabric, not slapped on top. No cracking, no peeling, no fading — wash after wash, roll after roll.
A Fit That Disappears
Compression cut that moves with you and stays locked in. No riding up, no distractions — just you and the next submission.
Roll Risk-Free
Not feeling it? 30-day no-questions returns and exchanges. If it doesn't earn its spot in your gear bag, send it back.
Technique Decays. Discipline Remains.
