The colonial duster is a lightweight, loose-fitting and lightly armored, militia-styled coat. There is a purple vest and heavy scarf underneath it. It has a leather bullet pouch around the shoulder and a small pouch on the belt but these do not increase Carry Weight or provide any buffs.
It is worn by Preston Garvey. The colonial duster can be obtained by the Sole Survivor 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 level 3 clothes emporium in a settlement, providing unlimited supplies of this outfit as well as the matching hat.
Behind the scenes
The colonial duster was modeled by character artist Jonah Lobe.
