ABSTRACT OF THE DISCLOSURE Protective headwear is described which provides protection against radio-active contaminants, or chemically or bacteriologically polluted atmospheres, (i.e. A B C environment) This headwear protects a user's head and respiratory system, and is fabricated of a material resistant to the A B C environment. An A B C proof visor is mounted sealably in a from t portion of the headwear, frequently in the form of a hood, with the lower edge of the visor being detachable from the hood material. The visor can thus be lifted. The hood also has provisions to prevent the atmosphere outside the hood from reaching the head via the neck region. This arrangement permits the wearer to breathe acceptable air and/or oxygen. In a preferred form the headwear is in the form of a protective helmet. In another preferred form the protective headwear includes a flexible skirt to overlap the wearer's shoulders, and even more preferably has a breathing mask therein.
