How is the EVA so thin? You’re telling me this whole time we never needed these chunky bois?

No clue really since I don't think there's too much information about the SpaceX flight suits, however theirs (like all flight suits) isn't fundamentally the same thing as an EVA suit, there's no PLSS, there's no hard components outside of the helmet, and it's only function would be to prevent the astronaut from dying in the event of depressurization, it's not intended to spend long periods of time in hard vacuum, so the requirements aren't as rigorous, basically it just has to hold one atmosphere of air inside and circulate that to the wearer. EVA suits on the other hand have a hard cuirass made of some composite material onto which the PLSS, helmet ring and other hard components of the suit are attached, a special undersuit is worn to regulate the astronaut's body temperature so they don't overheat, and the whole suit is protected by several layers of insulation (for heat) and kevlar to protect against cuts.

I think though that it's safe to say any modern suit will have significant advantages over the EMU, considering that it's design is closing on half a century old, I'd expect the PLSS to be reduced in size, and the dexterity of a modern suit to be greatly improved.

Why do modern space suits still look pretty much the same as those from 50 years ago?
