Prototype Cold Weather Face Mask
Abstract
An improved cold weather face mask has been developed which should provide protection from cold, wind, blowing snow, and frostbite in environments to -65F and 35 mph wind velocities. The mask provides physical compatibility with military clothing and equipment and will not occlude the field of vision. It weighs less than 2 1/2 ounces, covers the forehead, cheeks, nose, ears, chin and mouth, and is designed such that a single-size mask can adequately accommodate the U. S. Army population. Provisions are included to permit eating, smoking, relief of excess moisture accumulations, and elimination of oral and nasal body wastes. The mask is composed of a laminated insulating material facepiece, an oronasal thermal control barrier and an adjustable retention harness. The laminated material consists of a stretch nylon outer layer, a cotton jersey inner layer and an insulating interlayer. In the final configuration, mask models were produced using either a 1/4-inch polyurethane foam or a 3/8-inch polyester felt for the insulting interlayer. The laminated material has sufficient compliance and stretch to conform well to a wide range of facial contours.
