...It's not clear if micrometeoroid protection is required on Mars to the same extent. The thin atmosphere might provide some protection.
It seems like many people here doesn't know what a flight suit is, and what it's for. You should take a look at those videos:
http://www.projectrho.com/public_html/rocket/spacesuits.phpI was trying to find a side by side comparison of movie space suits, maybe someone with better google fu can look.
I wonder if that illustration was done by Stanley Von Medvey aka 'bagtaggar'. He has made some nice looking digital paintings featuring SpaceX in past.
As an extra level of protection, the crew will wear SpaceX-designed spacesuits to protect them from a rapid cabin depressurization emergency event of even greater severity. The suits and the vehicle itself will be rated for operation at vacuum.
A pressurized flight suit for Dragon 2 in case of decompression is not EVA. And what you need for a spacewalk is not what you need on the Moon, and certainly not for Mars. SpaceX has a Dragon suit. Is not clear if they want a Mars suit themselves. They would not do Moon or EVA, either.
A spacesuit designed for EVA requires protection from vacuum, radiation

That would be vacuum in either case..."Radiation" of different types tends to have wildly different penetration abilities. Alpha, beta, and not very fast protons are easy to shield from, and even ordinary dense clothing would do. On the other end of the spectrum of "badness", 1-10 MeV gammas are nasty. Any practical spacesuit can't shield those (you'd need several centimeters of steel to attenuate them even just x2).

There is a mobility requirement differences between protection from depressurization event in the vehicle and EVA 2. There is solar radiationand heat removal, micrometeoroid protection,
