Hi Cave,
Like Gary, my mask was also thermo-formed plastic. I hated the idea of being restrained but my best-friend and caregiver convinced me that it should be looked upon as a friend that was around to contribute to saving my life.
Good Luck and like Chuck says, keep coming back. We are all with you.

Jack
