CILL is a competitive men's indoor lacrosse league based in arvada colorado.


Established in 2005 by a bunch of guys playing pickup indoor lacrosse that wanted to take the league to the next level.  A board was established and the name was chosen.  Since then the league continues to grow from pickup indoor lacrosse with outdoor rules to REAL indoor lax with multiple referees, score/stat keeper, and shot clock.
