Vault Jumpsuit (Fallout 4)

The vault jumpsuit is a piece of clothing in Fallout 4.

Characteristics
This piece of apparel was the required clothing for every vault and is comprised of a light blue jumpsuit with a yellow line around the neck, middle and sleeves. It increases Energy Resistance by 5 and Radiation Resistance by 10 when worn.

The yellow stripe on the suit is actually a gold foil that aids in heat dissipation and works with the suit's integrated biometric scanners.

Numbered vault jumpsuits
Vault jumpsuits are worn by the inhabitants of the vault that is represented by the number on the jumpsuit.

There are eight numbered vault jumpsuits in Fallout 4, including the Vault 101 jumpsuit that is not present in the game, the Vault 75 and Vault 95 jumpsuits which are unobtainable without console commands or mods and the Vault 118 and Vault 88 jumpsuits that require their respective add-on.

Vault 81 jumpsuit

 * Vault 81, worn by the residents.
 * A total of 32 can be obtained by either pickpocketing or murder.
 * Bobby De Luca's can be obtained without committing a crime, if he is insulted and turns hostile during Dependency.
 * If Tina De Luca is recruited to a settlement, her vault jumpsuit can be obtained by trading her a different outfit and equipping it.
 * Trader Rylee wears one, but it cannot be obtained without pickpocketing or murder, even if she is recruited to a settlement.
 * One can be acquired from an NPC in a random encounter, that serves to make the player character aware of the existence of Vault 81.

A child version is worn by the children of Vault 81, which lacks the Energy Resistance of the adult version. If one leaves and comes back, all of the guards and overseers will spawn with a new suit but the other residents will not.

Vault 88 jumpsuit
One jumpsuit can be found inside Vault 88 on a Vault 88 steamer trunk near the vault door entrance. The steamer trunk itself contains 10 more and has its inventory refilled as soon as one exits the vault. 20 more can be found in the workshop inventory. Lastly, the Legend of Vault 88, a unique version of the jumpsuit, is rewarded upon completion of Lady Luck. Unlike all other vault jumpsuits, Vault 88 jumpsuits (with the exception of Legend of Vault 88) have no value.

Upgrades

Behind the scenes
The vault suits in Fallout 4 appear to have been based on a mix of the vault jumpsuits from the Interplay era Fallout games and the Bethesda generation vault jumpsuits.
