I don't know if this is planned but I wore the Sierra Madre Reinforced Armor to OWB. It seems as if this DLC could not read the Damage Resistance of the armor. I was getting hit 2 (sometimes 3) times by a Lobotomite's Brush Gun or Hunting Revolver and down for the count. The armor was not damaged when I left the SINK (I made certain that it was at 100% when I got outside) It was as if I was in my underwear and yes I did take off the armor on one of my rather fustrating reloads and the same thing happened-2 hits and down.
