Environmental Armor

Environmental Armor was developed for use in heavily contaminated environments, and is prized in the wasteland for its ability to protect against biological threats. This Armor affords the wearer 60% protection against harmful airborne agents and radiation. A superior version of this armor is Environmental Armor Mark II.

Eastern Brotherhood of Steel Knights are sometimes dressed in Environmental Armor. This protects them against radiation, chemical and bio warfare agents. Of course, it also helps with the Brahmin smell.

Appearances in games
Environmental armor appears only in Fallout Tactics. It was to appear in the canceled Fallout d20 as well. It is described in J.E. Sawyer's Fallout Role-Playing Game, so it might have appeared in Van Buren as well.
