artreides is a race of people from the planet artreides(obviously) in the world of dune. there are 2 others: harkonnen(brutish-industrial) & ordos(techno-economy). actually ordos is hardly or maybe never mentioned in frank herbert's books. this i'm not so sure. dunyain may know more.

referring to the first post, the helm has both poison resistance & skin of poison(useful especially for the wrestling & merc guild quests). don't know why artreides is connected to poison but then maybe it's just namesake.
