Ronin was founded in Brooklyn, New York, by fighters who trained BJJ and wanted gear that matched how seriously they approached the sport. The name comes from the Japanese term for a masterless samurai — a fighter who answers to no one but their own discipline.

The brand draws from three traditions: the Japanese martial arts that gave BJJ its roots, the Brazilian academies that developed it into a competitive sport, and the New York fight culture that shaped its founders. That combination is reflected in every gi — in the construction, the materials, and the way they hold up under daily training.
