GET MORE > When your day is long and your class too short, Go to the OPEN MAT. The OPEN MAT welcomes all Students, Associations and Instructors alike. Respect, If you have a current Associtation, we don't want you to leave them, we love them all. We just wish to provide you longer hours of mat time to improve your game 7 days a week. When classes are not available at your home Academy, make OPEN MAT your home away from home with an OPEN MAT Pass!
