> However, even at the top of Everest it’s nowhere near a vacuum; so the air pressure differential and therefore the stiffness would be a lot less.

The air pressure difference is whatever you need. In space the the pressure differential is 30kPa, since they run pure oxygen (Plus allowing for CO2 and water vapour). Top of Everest is 34 kPa. So if you run pure oxygen at the top of Everest you don’t need any pressure differential at all. So why are you wearing it?
