Vault 101 utility jumpsuit

The Vault 101 Utility Jumpsuit can be found in your bedroom, or on the corpse of Floyd Lewis, inside Vault 101 during the Quest Escape! After that, you can receive a Modified Utility Jumpsuit (which is similar in appearance, but different in skill/stat modification) by completing the quest Trouble on the Homefront without the use of violence.

These suits are modified versions of the standard jumpsuit designed for menial labor and routine repair and thus feature some changes:


 * An unzipped top section to help remain cool in the reactor levels and other systems which produce high levels of thermal energy


 * The gauntlets are removed presumably because they would become scuffed and dirty with constant contact with chemicals and lubricants


 * The sash on the left shoulder and breast are removed possibly to indicate that the maintenance division is the lowest rank in the vault


 * The jumpsuit is extremely grubby presumably due to waste rubbing onto the suit from their work


 * Based on the fact that when you leave the vault if you look in your dresser you will find a maintenance suit regardless of your expected job suggesting it may be a backup or relaxed version as well


 * Despite being a more functional version the suit features 60's style high-top sneakers which would be less functional than the boots the regular version comes with which suggest that Vault-Tec intended for the maintenance teams to stay in their vault keeping the power,computer and life-support systems running while guards doctors and citizens explore
