Armored Vault 101 Jumpsuit

The Armored Vault Suit (also referred to as Armored Vault 101 Jumpsuit) is, as the name suggests, a version of the regular Vault-Tec Vault Suit modified to better protect its owner in combat. It cannot be repaired with any other armor, and thus must be repaired by NPCs.

Obtaining
The suit can be found in Craterside Supply, Moira's store in Megaton. Moira bestows this gift on the player after complying with a request to recall how life in Vault 101 was. While it has the name Armored Vault Suit, it appears to be a normal Vault Jumpsuit with several metal 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. Moira explains that she made this suit for a girl from the Vault around "10 or 12 years ago," but the girl never returned to pick it up, leading Moira to speculate that she may have died. The way the suit is displayed in Moira's store is somewhat similar to the way you find the Vault 13 Dweller's suit enshrined during Fallout 2.

It can be stolen from Moira's shop if you chose to not help her with the Wasteland Survival Guide.

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.
