See link for an image of Norts in a comic book.Ther mask/hood as drawn there looks wrong to me because: * There is no room for his nose. * The breathing tube stubs are a long way from his mouth and nose. As the hood is all soft, when he breathes in, he would suck airtight hood material against his mouth and nostrils and suffocate. Or should I get more like the comic? After 40 years associated with scuba diving I know something about what works and what does not work in breathing apparatus.

Likewise I feel uncomfortable about the comic's version of his breathing set; it is the far-too-common comic-book wrongly-drawn aqualung without regulator (see http://en.wikipedia.org/wiki/Diving_regulator#Twin-hose_without_visible_regulator_valve_.28fictional.29 ) which would not work in the real world, with influence from a US Army flamethrower (see http://en.wikipedia.org/wiki/Image:Usafl_rend.jpg ). A backpack box would protect the parts from damage, and avoid the artist having to design  the breathing set's working parts. To me, the type of breathing set with long duration and easily refillable in field conditions would be a cryogenic rebreather (see http://en.wikipedia.org/wiki/Rebreather#Cryogenic_rebreather ), which would need liquid oxygen and nothing bulky else; their support vehicle would carry a machine to extract and clean oxygen from atmosphere and liquify it. Or should I get more like the comic?
