|For an overview of various Vault jumpsuits in the Fallout series of games, see Vault jumpsuit.|
It is the standard attire for all children in Vault 101 and presumably all youth participants in the vault experiment. The Lone Wanderer is equipped with this suit during their childhood in the vault.
The jumpsuit is only accessible as a child unless certain console commands are used.
- The jumpsuit looks exactly like the normal Vault 101 jumpsuit, except it's smaller in size, it has a less utilitarian belt, doesn't have the various pieces of equipment on it and the pants are not bloused above the boots.
- Even though it does not have the attached equipment, the child's jumpsuit weighs more than the adult-sized jumpsuit.
