Stars and Stripes bandana

The Stars and Stripes bandana is a piece of headwear in Fallout 4.

Characteristics
It provides no damage resistance and is purely a cosmetic item - however, it is counted as a piece of lower headwear, which allows the user to equip any sort of upper headwear at the same time. It can be equipped by Dogmeat.

Locations

 * One can be found inside Monsignor Plaza, on a shelf behind the counter of the clothing store, located on the first floor.
 * Can be found on the body of Ruby

Behind the scenes
Interestingly enough the Stars and Stripes Bandana features the real world American flag, not the In-universe one.
