BOS Uniform

The BOS uniform is a piece of clothing in Fallout 4. Some variants are unused and only worn by NPCs.

Gameplay
The uniform was originally intended to be worn as underarmor while wearing power armor. It comes in three different variants; orange, olive green, and jet black, with all three variants having the same defensive stats, weight, and value. The BOS uniform allows armor pieces to be worn over it, but it may not be modified at a workbench.

Locations

 * The orange-gray variant is sold by Proctor Teagan. It is by worn The Scribe and by Paladin Danse who wears it under his power armor and can be obtained through trading.
 * The olive variant is worn by Clarke and random unnamed Brotherhood soldiers.
 * The jet black variant is worn by Paladin Brandis any time he is encountered outside the Prydwen, specifically during the quests The Lost Patrol, Precipice of War, Airship Down and Ad Victoriam. It may also be found on Brotherhood soldiers during The Battle of Bunker Hill.
