They can be repaired with other copies of themselves, or by obtaining one of the various wasteland outfits (see infobox), in which they provide a Damage Resistance of 2, as well as bonuses of 1 to Agility and Endurance.
Tattered slave outfit
The tattered slave outfit can be obtained at the beginning of The Pitt, from a slave named Prosper. The add-on gives the choice of either obtaining it from a dead slave in the slave pen located at the train tunnel, or by requesting one from Prosper himself. If worn, when meeting Mex at The Pitt entrance, he will mistake the Lone Wanderer for a slave.
Worn slave outfit
The worn slave outfit is identical to the tattered one, with the only difference being that is a dark brown color.
Sometimes when a black player character equips the outfit, they will have a white body, with only the head and neck being black. [verified]
