I always assumed that a Tie Fighter was airtight until it had a hull breach, by that point having complete separate support is completely advantageous. It also allows the pilot to survive in a very small ship for extended periods of time without investing in ship wide life-support systems when they have their life support on a much more personal system. This saves costs in manufacturing a ship wide life support system and allows the empire to remain a streamlined engine of war.

This is the both ways answer; there is air in the cabin, but probably not enough for prolonged military exercises thus most pilots are seen wearing space suits as standard as both safety and efficiency feature.

The alternative answer is that Rebels is a cartooon and ultimately it will cater to it's primary audience, the children that they want to draw into star wars, they don't really mind the small details and are more about making entertaining viewing. I always took a very simplistic view on canon; I don't really care as long as it's entertaining.

Which happens to be the model modern fighter aircraft use. There is also an advantage to positive pressure masks in high g maneuvers.

Considering the orignal triolgy's dogfights were heavily based WW2 counterparts, it only makes sense that the tie pilots drew similar inspiration from modern pilots of the time.

Modern fighters aren't air tight and the masks are needed as you go up in altitude. Yes, they are pressurized, but the internal pressure isn't guaranteed to stay at a breathable level, unlike commercial aircraft, as it helps reduce the stress the airframe is put under, which is bad enough from pulling high Gs.

There is a bit in a star wars novel series where a pilot infiltrating a tie unit was in standard tie helmet, the hose was damaged by an impact that slammed her into the side of the cramped cockpit, it mentions her overloading the system that circulates air through their breath mask to keep her conscious long enough to make it back to the star destroyer. Basically, there is some air in the tie because of the way it seals but not enough to do much, though i might be remembering it wrong.

They don't actually have anything in current "cannon" specifying the cockpit conditions inside the tie

One thing to consider. Rebreathers do not last that long. They just scrub the co2 out of the air you have. Last maybe a couple hours. This is not that useful for a fighter pilot who needs to do about 8 hour patrol. Which happens in todays military. So I suspect like today's planes they have life support you plug into. Just makes sense. And I am sure TIES are also airtight. So one could easily make a short jaunt without the flight suit.

These are also fighters with days of consumables.

Staying in a fighter like an X-Wing for days/weeks opens up other topics for discussion...human-waste wise. But those problems are not part of the ruleset in most RPG's...luckily

Uh... This goes in your mouth. This one goes in your ear. And this one goes in your butt. (Wedge puts wires in, droid beeps) ****. Hang on a second. This one... Uh... This one... this one goes in your mouth.
