Abstract: An air heater ski mask having apparatus to preheat incoming air. The ski mask comprises a cold weather protective hood adapted to fit over the wearer's head, and having eye and mouth openings. The breathing apparatus fits within the hood and is configured to permit a helmet to fit over the wearer's head when the hood is in place. The breathing apparatus fits within the hood and is elongated, having an intake positioned behind the wearer's ear where the air is relatively warm. The intake air passes through an intake valve to a nose piece and exhaust air exits through an exhaust valve adjacent to the nose piece. An exhaust tube surrounds a portion of the intake tube to preheat incoming air.
