Robotic bits

The  is a cut piece of clothing in Fallout 4.

Characteristics
It provides a Damage Resistance of 0 as well as a bonus of +1 to perception. It appears to have been a piece of "armor" that Nick Valentine would have on him, or possibly drop as a death item, however it is never referenced in the code. On the body it takes up the eye slot like sunglasses. If added to inventory via console, it won't appear in the Pip-Boy.
