I own a Save Phase mask which was given to me two years ago
and it's strictly a face mask. That's not to say they don't make
a version that has full head protection.
What makes the Eye Tactical mask/helmet model unique, is the
way it fits to the helmet and the fact that there's also throat,
neck, cheek area flexible nylon mesh guard which you can snap
out and wash or leave off if you wish.
