I mean, to be fair, in Star Wars movie canon [url=https://www.youtube.com/watch?v=9AKMLJ6UTo0]you only need a little breathing mask to survive in space.[/url] I mean, they didn't know they were inside a giant worm, so it's safe to assume that, even in the cold recesses of space, those little facemasks would work.

In that particular case, I’m more inclined to believe that the worm’s belly generates a more hospitable atmosphere. Like, it has to be pretty warm inside a living being. And subsequently, the stomach gasses could make it easier on the eyes and such. You certainly got a point that their ignorance of the situation still informing such minimal precautions does certainly say... something.

Although, as a small argument for your idea, remember that Grievous’s fully organic eyes have no shielding. Then recall he blasted open a hole in his flagship in Episode 3 and walked on the outside of it to no apparent harm. Of course, he presumably has a breathing apparatus built into his cyborg-ness to cover him on oxygen, and it’s possible Kaleesh biology is more forgiving/hardy than human, but the point stands.

And I suppose if we acknowledge the sequel trilogy, we can recall Leia getting blasted out into space with no protection whatsoever and surviving. Granted, she was using the Force, so it’s also possible that it was protecting her from the hostile environment as well.
