Tesla armor (Fallout)

Tesla Armor is a type of metal armor that makes its wearer resistant to energy weapon attacks.

Background
Unlike the basic metal armor it strongly resembles, this armor is an actual pre-War military design, constructed from plans left behind by Nikola Tesla, confiscated by the US government after his death. It is designed to protect the wearer against energy attacks - three Tesla Attraction Coils disperse a large percent of directed attacks. However, since its protection against conventional firearms is comparable to the post-war metal armor, its popularity was limited, although some suits made their way to National Guard depots and from there to the wastes.
