A breathing helmet was an apparatus designed so that certain beings requiring an atmosphere could breath in harsh environments.
Darth Daniel and Noah Tolmach wore types of these helmets during the fight around Iapetus on August 3, 2014, so that they could breathe in outer space.
Heads-up-display[]
The helmets had a heads-up display that allowed the user to view their surroundings by having physical things pointed out, have faces scanned, to view images or play music.
Artificial intelligence[]
The helmets had an artificial intelligence that allowed the users to talk to their helmets, which often had a limited personality. Noah Tolmach used an AI called A.L.I.C.E. to help him control the helmet's functions, whilst Daniel's AI was named S.E.B.I.
Behind the scenes[]
The helmets they wear resemble those of the Star Wars films' clone troopers and Darth Vader, respective to the above order. On the day of filming Episode III, Noah gave Daniel a choice between three helmets: the clone, Vader, or Boba Fett, the latter of which wasn't used until Noah's armour.
