Grit, guts, and GIRLS Hockey. The CCM Girls World Invite hosts over 2,000 girls, battling it out for all the glory on the ice. We expect Tier-I and Tier-II teams from the United States and Canada to convene in Detroit in a three-day spectacle, toughing it out in over 250 games. It doesn’t get bigger than this for girls’ Hockey. Will you join in on the madness in Motor City?
