ABSTRACT:
A breath controller prevents fogging of the face shield of a helmet during cold weather. The breath controller comprises a facepiece that fits comfortably over a person's chin, mouth, and nose. One end of a sleeve is held in a sole opening in the facepiece at the chin section thereof. The sleeve second end terminates well below the lowermost edge of the helmet. The facepiece and sleeve cooperate to direct the person's breath between his nose and mouth and the atmosphere such that no exhaled breath comes in contact with the inside of the helmet. In a modified embodiment of the invention, the sleeve is replaced by a short retainer and a cap that is removably attached to the retainer.
