Thindithron the Great wrote: Since when did the Nine wear armour, Grievous? Only helmets and robes, as far as I remember. "But suddenly he too stumbled forward with a cry of bitter pain, and his stroke went wide, driving into the ground. Merry’s sword had stabbed him from behind, shearing through the black mantle, and passing up beneath the hauberk had pierced the sinew behind his mighty knee."

So who knows about the others, but the Witch-King wore a hauberk.
