Colonial Duster

The colonial duster is a piece of clothing in Fallout 4.

Locations
It is seen being worn by Preston Garvey in the Museum of Freedom. The colonial duster can be obtained by the player if they have Preston Garvey as a companion. The player character can then force Garvey to equip another piece of armor, making the duster obtainable.

It can also be sold by Anne Hargraves if appointed to a clothes shop in a settlement, providing unlimited supplies of this gear and the matching hat (Preston's).
