It's not clear if micrometeoroid protection is required on Mars to the same extent. The thin atmosphere might provide some protection.
It does. Except at very high altitudes like Olympus Mons, anything you'd call a micrometeroid is going tens of m/s at most, and the big ones would break up. Vast majority of them would be going single-digit m/s, falling like sand on Earth. You don't need micrometeoroid protection on Mars.

SpX Mars suit worn by Elon Musk?
BFS in the background?

Is this a Martian rescue fleet arriving on Earth after a comet slam?

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:

Don't think the suit Elon is wearing is a flight suit.

I was trying to find a side by side comparison of movie space suits, maybe someone with better google fu can look.

Maybe a bulked up, harder version of Mark Watney's Mars surface suit?

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.

So apparently, it recently came out from a Hollywood superhero costume/prop designer that SpaceX had hired him to help in the design of their spacesuit, to give it an appealing aesthetic. Here's a pre-engineering concept pic:

http://www.techspot.com/news/64685-elon-musk-spacex-renowned-superhero-costume-designer.html

http://www.popularmechanics.com/space/a20713/superhero-suit-designer-spacex-spacesuit/



So obviously that's before they have to re-engineer it to fulfill the actual physical criteria.
This concept is just for aesthetics only, and the final product would look different.

Who knows how much of it will be discarded, but it's still an interesting base look. All you need is the right motorcycle to go with it.  ;)

Musk apparently wanted something that would look superhero-like -- ie. something that would look very attractive, stylish and cool, as opposed to drab, dumpy and goofy. In an interview some time back, Musk gave his perspective, explaining that aesthetics matters:





I wonder what stylistic/aesthetic elements will be preserved, while they modify it to make it actually functional.

What limitations and constraints will physics impose on achieving this look? There's been a lot of technological advancement since spacesuits were first invented. Can the suit really be made anywhere near that thin? I've seen some of those counter-pressure suit designs, including that one by shown by MIT's Dava Newman:




Where will the greatest challenge be in combining function with aesthetics?

Will SpaceX's spacesuit have any performance advantages over current-generation spacesuits?

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.

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.

Is it feasible/possible to have an all-purpose/multi-purpose suit that would work for all or most occasions?
Or would such a suit be unnecessarily unwieldy?

What are the differences in the needs of the various types of suits for these different activities?

Apollo suits are the ones that spring to mind as the most versatile.  Since then, suits have been either for depressurization events (Russian suits on Soyuz) , depress and bailout (shuttle and Air Force high-altitude) or zero-g EVA type suits.  China copied the Russian models, more or less. 

The weight, bulk, expense and complexity go up fast as you increase the number of tasks a suit has to perform.  The Russian suit for instance, only has to function while the wearer is strapped into a Soyuz couch.  It doesn't have to provide radiation shielding, elaborate thermal control in extreme temperatures or mobility other than reaching the controls.  It's just to keep you alive in the capsule until you get down to the ground

A flight suit is usually lightweight and designed for surviving a depressurization event in the vehicle. ACES used on Shuttle flights was only 12.7 kg without all the survival gear and parachute.

A spacesuit designed for EVA requires protection from vacuum, radiation, etc. and life support for several hours. The Z-1 was 57 kg and the Z-2 was 65 kg without their PLSS for life support. The Shuttle and ISS EMU is about 50 to 55 kg, depending on the model.

So, an EVA suit is about five times greater mass than a flight suit due to the extra layers of protection.

If you had a PLSS for your flight suit, you could do an EVA, but it would be more dangerous.

Can someone provide more substance?

How "vacuum" is different from "depressurization event in the vehicle"? 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).

Think of it as the difference between snorkeling and real diving gear.

Good points. I should have wrote micrometeorites and temperature change.

1.  There is a mobility requirement differences between protection from depressurization event in the vehicle and EVA

2.  There is solar radiation
