Plural of clad; multiple pieces of protective clothing or outer garments, or to dress someone in clothing.
From Old English 'clathan' (to clothe). 'Clad' evolved as both past tense of clothe and as an adjective meaning dressed or clothed in something.
The word 'clad' is doing double duty in English—you can say 'he clads the armor' (verb) or 'he is clad in armor' (adjective)—which is why English is wonderfully confusing and efficient simultaneously.
