Shady Hat

The shady hat is a unique, fedora-style pre-War hat in Fallout 3.

Location
The shady hat can be obtained as a reward for doing the Mirelurk Observation quest as in Moira's quest "The Wasteland Survival Guide". To get it, the player must place an observer unit in a mirelurk egg nest without killing any of the mirelurks in the area.
