spacesuit

I'm currently wondering why we dont have armored helmets and body suites? i mean like N7 type stuff, or Lost In Space stype armor/helmets.

I made this post just for fun, after reading an article about scuba diving (lol!). Answer is probably: Coz it's a game. It is currently year 3303 in ED, How is it possible that the best life support emergency oxygen supply (class 4) can only last for 25 minutes? We don't even have to discuss...
