As a note:
Smoke hoods cover the entire head.
Some airlines use full face masks, others use nose-mouth masks and separate eye covering modules.
I advise any pilots who don' t have on-board eye-protection equipment to carry tight swimming goggles along when you fly.
Irritating smoke in the cabin can blind you.
You don' t know when that Cessna or Piper is going to start smoking.
It' s better to be ridiculous when someone finds out that you carry one than to be dead.
