Some armor designs for my two War Boy characters, Big Boy and Backpack.
Big Boy is a bona fide wasteland gladiator and he's got the armor to match. He fastens the chains of captives to his belt during battle, and wields his massive size and strength to deadly effect.
Backpack is very small compared to Big Boy. To protect himself in battle he wears a spiky "coyote vest" of scrap metal to keep his enemies at bay.
