A head portion has an open front portion through which a face mask extends. The front portion is elastically biased into engagement with the mask to provide a good seal between the front portion and the face mask. A skirt extends from the lower part of the head portion and flares downwardly and outwardly to overlap the collar of a firefighter coat to provide a good seal with the coat and prevent entry of debris between the skirt and the collar. A flap has one end permanently secured to the head portion and the skirt; and the opposite end of the flap is detachably connected to the head portion. A thermal liner is permanently secured to the head portion and skirt and is spaced from both the topmost part of the head portion and the opposite end of the flap.
