Armored Vault 101 Jumpsuit

The Armored Vault Suit is, as the name suggests, a version of the regular Vault-Tec Vault Suit modified to better protect its owner in combat.

Appearances
The armored version of the Vault Suit first appeared in the Fallout outro movie, but it wasn't a wearable in-game armor until Fallout 3, where it can be found in Craterside Supply, Moira's store in Megaton. Moira bestows upon the player this gift after complying with her request to recall how life in Vault 101 was. While it has the name Armored Vault Suit, it is simply a normal vault suit, with several armored plates attached to provide additional protection. This suggests that Vault 101's Vault Experiment that "no one ever enters and no one ever leaves" was not quite true.This is possibly explained by the scouting parties mentioned in the overseer's computer, perhaps one left a jumpsuit as a gift? The way the suit is hung in Moira's store is somewhat reminiscent of the way you find the vault dweller's suit in the shrine during fallout 2.
