With all the weird superscience crap those 'frames do, you'd think adding independent life support at least for a hour or two would have been a trivial task...

Also, just about all of them have either a visor (think Mag) or a varying number of forward-pointing glowy dots in their helmets that can be reasonably assumed to be some kind of (visual) sensors. Doubly so as they're mostly distributed in a bilaterally symmetrical fashion for proper binocular vision...
