The present invention, the new and improved warm air mask, is a system 10 comprised of a plurality of components. In their broadest context, the components include a facial covering, inhale ports, an exhale port, electrical resistance wires, securement straps, fasteners and adjustment members. Each of the individual components is specifically configured and correlated one with respect to the other so as to attain the desired objectives.

More specifically, the system 10 of the present invention includes a facial covering 12. Such covering is positionable over the mouth, nose, chin and cheeks of a wearer. The covering includes an interior layer 14 of a stay dry material, preferably a flexible plastic. The covering also includes an exterior layer 16 of a stay dry material, also preferably a flexible plastic. In addition, for comfort there is provided an intermediate layer 18 of felt between the interior and exterior layers. The covering is configured to form an upper edge 20 positionable above the nose of a wearer, a lower edge 22 positionable beneath the chin of a wearer, and side edges 22,24 positionable beyond the ears of a wearer.

Three oval inhale ports 28, 30, 32 are formed in the covering. Such ports extend through the covering. Each inhale port including a fabric mesh 34 and an imperforate flexible flap 36, 38. Such flaps function independently to open with the inhaling of a wearer and to close with the exhaling of a wearer.

In addition to the inhale ports, there is also provided a single circular exhale port 42. Such inhale port is formed centrally in the covering and extending therethrough. The exhale port includes an imperforate flexible flap 44. Such port functions to open with the exhaling of a wearer and to close with the inhaling of a wearer. The plurality of ports and flaps thus work together to allow for breathing by a wearer.

An additional feature of the present invention is an array of electrical resistance wires 48. Such wires are provided for generating heat when electrically activated. The wires of the array are positioned in each inhale port with an associated electrical power source 50 and a switch 52 which are secured adjacent to the covering for selectively activating and inactivating the resistance wires. Appropriate electrical lines 54 couple the electrical wires, power source and switch.

Securement of the covering and its components are achieved by a pair of parallel securement straps 56, 58. Such straps have first ends 60 fixedly secured to one edge of the covering and second ends 62 separably secured to the other edge of the covering. The first ends are preferably coupled through snaps 64.

Pile type fasteners 68 are provided for releasably securing the other edge of the covering to the second ends of the straps.

The last components of the present invention are adjustment members 72. Such adjustment members are of a conventional configuration. They are preferably located on the straps intermediate the ends.
