FSO features kids gi and nogi divisions, women’s gi and nogi divisions, men’s gi and nogi divisions, multiple pre-scheduled high level superfights, and men’s and women’s nogi ABSOLUTE divisions. Our UNDERGROUND, SQUADS and SQUAD5 events feature high level teams from all over the United States and Canada, with in person tickets available as well as online streaming.
