Gas mask hoodie
A gas mask hoodie or gasmask hoodie is a hooded jacket with a front zip that extends up both sides of the hood. This means that when the zip is fully closed, the hood completely covers the wearer's face except for two eye holes. The eye holes may be covered with a mesh or even one way mirrors so that the wearer's eyes cannot be seen.
The name comes from the resemblance of the hood to a gas mask.
The term is also used for a hoodie with a picture on it of a man wearing a gas mask.
