Vault jumpsuits are clothing that appear in all Fallout games. However, in Fallout and Fallout 2 they are worn by the player character by default and in Fallout 3, Fallout: New Vegas, Fallout 4 and Van Buren, they appear as actual in-game items. In Fallout Tactics and Fallout: Brotherhood of Steel, they are not usable by the player character, they appear to be made out of a leather jumpsuit, the numbers are made of polyester and the belt and other components are aluminum.
