This unique suit was developed as an upgrade of the original environmental armor, for use in more heavily contaminated environments. It is composed of a full body suit worn together with a helmet with a black, polarized glass face plate, sealed and provided with air from back-mounted gas tanks. For combat, the suit is worn together with reinforced armor plates. The upgraded version features redundant gas tubes and industrial-grade filters on the mask.
Knights of the Brotherhood of Steel 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.
This armor affords the wearer 90% protection against harmful airborne agents and radiation.
Sold by the quartermaster after Jefferson (+1) and Osceolla (+3).
