Fill the new spacesuits with gel, then they don't need to be pressurized, which makes them much easier to move in :)
But much more messy to get out of. Showers being a bit of a luxury, if you make the gel from that powder that turns into a gel when wet, then turns back into a powder when dried, you should be able to get clean with a hair dryer and a vacuum cleaner.
Apparently it keeps quite cool too. And the volume of water involved might make a pretty useful radiation shield too, but would probably be quite heavy.
There's probably a million reasons why this won't work in reality, but it's fun to speculate :)
