I bet the astronaut would have to add a further heavy suit over the top to do EVA work?

Compared to the competition.

OK, but THIS suit does look pressurized.

Still, one major difference seems to be the helmet. Basically all IVA suit helmets up to now were fixed to the suit. The SpaceX helmet seems to be conforming to the head (like a motorcycle helmet), connected to the suit with a soft neck "tunnel". This means as long as the suit isn't pressurized you can move around your head (with the helmet) freely, look around and up and down, even nod and shake your head. You also are wearing a full, padded crash helmet.

This is an altogether good thing compared to all fixed hard or soft helmets where you can move around your head only INSIDE the helmet and have to try and look through the limited, unmoving visor in the front. I think the first Mercury spacesuit was a bit similar (but still with a neck ring with the helmet only able to rotate on it, not move up and down).

Ouch. That's a punch in the face of the David Clark company, by one of their former users no less. Not to mention that it basically disqualifies the IVA suit for Orion.

Yah, that disqualifies him from being objective... just like anyone working for NASA cannot be about NASA hardware.

What does pressurized mean? Obviously the wearer can breathe, so there is air inside.

I think the picture shows the nominal state, when the pressure inside and outside of the suit are equal.

The suit will surely become more bulky and stiff in a vacuum.

I was talking about the (blue) Boeing suit and pressurized means the pressure inside is higher than the pressure outside.

I agree that for an emergency suit the nominal state is the pressure inside being equal (or only slightly higher) to the pressure outside, but the Boeing suit definitely looks expanded while the SpaceX suit does not.

Wonder how SpaceX keep the helmet visor from misting over with their spacesuit.

Only the torso of the Boeing suit has this expanded look. Arms and legs look loose (e.g. wrinkled).

I can only go by the look, but I think there is some kind of stiff but not rigid armor (?) around the torso that gives this expanded impression.

The best way would be to stream the air pumped through the suit over the visor first to carry any moisture away. Good motorcycle helmets have some inlets around there to do that. Anti-fog basically is dish washing liquid to lower the surface tension of the condensing water so it doesn't form small droplets and a sheet of clear water instead, but you still get water gathering there.

They have to do that anyway or the wearer will suffocate on his/her own exhalations. No convection as such in micro-g. ;)

Further clarification on who is wearing the spacesuit:

Quote
The spacesuit of the future has arrived! This is our spacesuit manager wearing a working flight suit in Dragon.

Then inside the suit on the first picture should be Jason Tenenbaum.

The current suit is an IVA suit. For CCP there are no requirements for an EVA suit. SpaceX has no need for EVA suits until they actually go to Mars.

Much the same way as Boeing/David Clark do with theirs: by circulating conditioned air.

Not to interrupt the fawning, but how does that comment disqualify anything?
The IVA suit for Orion is a slightly modified version of the shuttle ACES suit. Given that one of the former users of the shuttle ACES suit now qualifies the SpaceX IVA suit as "much better" than the shuttle ACES suit....
I think you are smart enough to do the rest of the logical reasoning.

By that reasoning you can never be objective about Spacehab because you once worked with them.

https://www.merriam-webster.com/dictionary/disqualify
Definition of disqualify

    transitive verb

    1
    :  to deprive of the required qualities, properties, or conditions :  make unfit

    2
    :  to deprive of a power, right, or privilege

    3
    :  to make ineligible for a prize or for further competition because of violations of the rules

Clearly the first definition is the one to work with here and I don't see how SpaceX's suit being called better by SpaceX employee renders the IVA suit for Orion unfit. Just because there is something better doesn't mean it is unfit for what it is supposed to do.

Today, GR is uniquely qualified to make the comparison -- no one else has worn both AFAIK.  In near future, at least two active NASA astros will wear these new suits; we will then see what they think.  (Unless we need to disqualify them because they work for NASA...)
