X Flag Football was started in the Summer of 2007 by five experienced flag football players. These players have played in different adult flag leagues in Southern California for many years. After realizing that a lot of the leagues were putting profits first and not the players, XFF's founders decided to create a league "by the Players, for the Players."

XFF Mission Statement
X Flag Football is committed to providing a year round, organized flag football league for its players. XFF will provide a suitable environment for the players, their friends, and family who attend the games. XFF respects its players and their viewpoints. We will not censor, condemn, or discourage anyone from expressing their ideas and comments as long as they are presented in good taste.
