[One Punch Man]Saitama may be invulnerable but why don't his clothes burn up when he fights the Alien Pirate King, who uses attacks capable of disintegrating matter? How does his exercise-regiment-related-powers empower his clothing?

Only at the very, very end of the fight after the Alien Pirate King uses his most Super Duper Ultimate Attack +24 are Saitama's clothes damaged and only then, only a little?  It is also unclear if that is from the alien's attacks, or Saitama's.

So, why are his clothes so tough?

His clothes are made from 100 stitches, 100 knits and 100 weaves. Every day no matter how his hands hurt. He did stitches even when his hands were bloody. He kept knitting even when his knuckles started making weird clicking noises.

He woke up one day and noticed some changes. All the excess material fell off and his clothes were strong!

Guys fooling around with this new material science junk, they're never going to make it this far. Human clothes are strong because we can change them ourselves!
