Superman's suit is skin tight as to not be able to be ripped/torn by conventional methods. He has an aura around his body which is what protects him from normal weapons (and that's why bullets bounce off his chests, kids!)
Notice how occasionally his cape is torn to pieces because his cape is not inside of his aura to protect him. Nice little effect that is.
Yeah that pr1983 guy's right, Superman is the shiznit compared to stupid little pansy Batman.
"Waaa, I have a war going on inside of me which I need to deal with on my own, Boo-hoo..."
I hate Batman so much. Really. I hate him to pieces. Batman thinks he can have Supes, and he is SO wrong.

Batman swoops down to save a girl from falling to her death after the Joker throws her off a roof of a building, and as he is about to grab her, Superman flies over and takes her to safety. Batman is outraged.
Batman: "WHAT THE HELL DO YOU THINK YOU'RE DOING?!"
Superman: "Making your job look easy."
Batman swings at Superman and Superman sidesteps out of the way at the speed of sound.
Superman: "Typical. Throw another and I guarantee I won't move... And that every bone in your hand will be broken."

What more can I say?
