Soft suits also take forever to put on, they fight your every movement (making EVA work very fatiguing), and if you tear the suit skin you will die horribly in about 90 seconds.
When I say "fight your every movement" I mean "raise the energy expenditure to do a task by about 400%".
It would be the outer-space equivalent of those stubborn elderly hospital patients who insist on smoking cigarettes while wearing oxygen tanks. NASA tolerates low-pressure pure-oxygen pressurization in their soft space suits because they have no choice.
There is not a lot of research, but NASA seems to think that if an astronaut in such a suit got punctured by a micro-meteor and it caught fire, the main hazard is a fire enlarging the diameter of the breach, an astronaut-shaped ball of flame.
Soft space suits are only terribly encumbering, like wearing three snow suits at once. Disadvantages include the fact they can be punctured by a pair of kindergarten safety scissors, causing certain death.
Oh, and they can only use low pressure because high pressure will make the suit spread-eagle you like a Saint Andrew's Cross.
NASA astronaut always put on a transdermal dimenhydrinate anti-nausea patch when suiting up in a space suit, in case of drop sickness.
The chances of that are slight, but suffocating inside a helmet full of vomit is a nasty way to die.Disadvantage is they have to use low pressure so The Bends once again raises its ugly head.Also people have a problem getting anybody to take it seriously A space suit is a protective garment that prevents an astronaut from dying horribly when they step into airless space.They are only used as a precaution, worn inside the habitat module during times when there is danger of it springing a leak (such as during lift-off).Full-(Body) Pressure-suits can be either Low-Pressure (pure oxygen at 32.4 k Pa) or High-Pressure (breathing mix at 101.3 k Pa, normal Terran atmospheric pressure).The accuracy of space suits in science fiction was very much hit or miss.
