About superman's suit. I've just always assumed that most things from krypton are pretty much indestructable because of their exposure to krypton's red sun and who knows what else because of kryptons giant size.
Saw a superman comic once where he had to make his CK glasses with glass fragments from his crashed ship because normal earth glass couldnt take the stress of his X-ray and heat vision.
I'm guessing it would be the same with clothing from there. I dont think he wears the suit because he needs protection, he wears it because it can take the punishment from what he does.
Who knows. Maybe snyder will play into the whole *aura* thing in this. anything within so many centimeters of supes body is protected. I would prefer that its explanied because the suit is from krypton tho. we shall see.
