ABSTRACT:
A compact and easy-to-use protective enclosure having normally open opposite ends and an identical elastic collar surrounding each end. The enclosure is sized to extend between the head and neck of the wearer and provide a self-contained supply of air from which to breathe when it is desirable to isolate the eyes, nose and ears of the wearer from a hostile environment. The first end of the enclosure is closed against the wearer's neck by the elastic collar surrounding the first end, and the opposite end of the enclosure is closed against the wearer's head by the elastic collar surrounding the opposite end. The first and opposite ends of the enclosure may be tightened around the head and neck of the wearer by pulling on respective attachment straps affixed to the collars so as to correspondingly reduce the areas within such ends. The enclosure is provided with optional filters covered by tear-off strips that may be removed when the enclosure is worn in a non-poisonous environment.
