Big Dan Manasoiu personally designed the Arrhichion kit to wear at the 2026 ADCC World Championships. From the dark, battle-worn artwork to the ancient Greek inspiration, every detail was built around the look Dan wanted for the biggest stage in submission grappling.
Dan also chose a unique 3/4 sleeve cut that gives you extra protection from mat burn around the elbows while keeping your forearms free and the fabric out of the way when you're locking up chokes.
The Arrhichion Rash Guard is built with the same proven construction as all Gold BJJ rash guards, designed to hold up through hard training and competition alike.
Flatlock stitching helps reduce irritation and chafing, while mesh underarm panels improve breathability and keep the rash guard comfortable during long sessions. The fully sublimated graphics are built into the fabric itself, so they won't peel, crack, or fade over time like cheaper printed designs.
The result is a rash guard that looks sharp, performs under pressure, and is made to stay in your rotation for the long haul.
Arrhichion of Phigalia was one of ancient Greece's greatest pankration fighters, winning the Olympic Games twice before returning for a third title in 564 BC.
In the final, Arrhichion was trapped in a choke but refused to submit, using his final moments to dislocate his opponent's foot and force him to surrender. Arrhichion died from the choke, but because his opponent had submitted first, the judges crowned Arrhichion Olympic champion for a third time.
More than 2,500 years later, his story remains one of combat sports' ultimate examples of refusing to quit.
