Vault 111 jumpsuit

 is an clothing-type item in Fallout 4.

Characteristics
Although it offers no protection from physical damage, it remains valuable due to its radiation resistance. It reduces the radiation damage from creatures and ghouls, as well as during storms with lightning flashes. The energy resistance is valuable later on, once enemies with energy weapons are encountered.

Modifications
The jumpsuit has a single mod slot, for lining. The Insulated Lining is easy to get, but unfortunately there's no increase in radiation resistance until reaching Armorer 2.

Locations

 * Vault 111: Obtained at the start of the game. Other copies can be salvaged from the Vault.
