Wasteland Champion Tire Armor by swanboy. I imagine a tire would actually absorb a lot of force from blunt instruments. (It also blocks a lot of cutting weapons, it just needs a bit of padding underneath it)
I'd wear it if it had a longer skirt, with a jacket and leggings.but I'm not sure what the 2 belts and 2 necklaces are for. Grasberger Grasberger Bennett Felfor this looks like something you would wear!
