Thinking about what kind of tech Jason has in his helmet.
Ignoring the og bomb. For sure he's got voice modulator, which implies some sound proofing so the voice is mostly filtered through the mic, which also implies mics/speakers to pick up sound outside the helmet and filter it in, unless there's much less proofing around the ears, but it would still be muffled.
There's gotta be air filtration. If a toxin is released, he's not gonna take it off to exchange for a gas mask. But I can't recall any canon times he's been seen around a toxin with his helmet (granted I haven't looked), so just gotta assume. This also means the helmet is air tight, some type of latching devices around base.
Comms are a question of are they built into the helmet or separate. If he lost his helmet, it would mean losing his comms too, so I like to think that even if there's comms built in, he has an earpiece at least as a backup just in case.
Then there's the lenses/eyes. They've gotta be lenses rather than holes for the air tight thing, unless it's air tight only around the bottom half of his face. There may be a part inside that juts in to fit snugly over his nose and cheek bones, but that seems unlikely, unnecessary, and uncomfortable.
From here, it's all just speculations and head canons. Are they just lenses? Do they have night vision? Are they opaque on the outside? What other kind of tech could you fit in there? WayneTech, what can you do? I'm sure he'd have more leeway in his helmet than the other bats' lenses do, because he has room for proper wiring, whereas you're working with very limited microtech for dominos.
Speaking of, is he wearing two layers of lenses because of his domino? Can they flick up the lenses, or like slide them up in the dominos if they wanted? I feel like they would have to be malleable for that. Otherwise it's just an all or nothing deal.
Back to Jason, is there a coloured film on the world? Is he seeing the world just extra pale/white because of having two white lenses?
How the hell do one way glass/mirrors work? Can that apply to this situation? Can they be super thin?
I'm so sleep deprived.
