From the press conference:

> Menon: Since there is not an airlock on Crew Dragon, the whole crew will be exposed to the vacuum of space for the EVA. [1]

> Gillis: For Polaris, "the suit that we're going to be designing will be a single suit that we would launch and then similarly use for the EVA." [2]

Sounds to me like one crew member will wear the EVA suit for launch and for the EVA, and the other three will wear flight suits for launch and while the capsule is depressurised. So only one EVA suit, no changing suits in space, no airlock.

That’s even more interesting. I wonder if components inside the Dragon capsule need to be rebuilt to handle cold vacuum. Or is that a standard design?

A vacuum inside a spacecraft is not necessarily cold, nor is the vacuum outside the spacecraft. Components may even begin to overheat in the absence of circulated air.
