ABSTRACT:
A full body garment made of flexible, non-stretchable, air impervious material which can be supplied with breathable, ventilating air from a remote source, for protecting a wearer when present in a contaminated atmosphere is disclosed. The garment includes a loose fitting body suit containing a shirt portion having two separate inner and outer layers of long sleeves, a manually cinchable neck opening, a long pants portion having separate inner and outer layers of legs joined together at and extending below the knee region, and a pair of gloves and foot covers joined in an air tight manner to the inner layers of the sleeves and legs, respectively. A loose fitting parka is also included which contains a slip over torso covering portion having sleeves with elastic bands around open ends thereof and an elastic waist band, a respirator hood, and a shoulder, upper chest and back encircling bib. A back portion of the suit contains a pair of exhalation valves for expelling excess air from the suit into a space between the shirt and torso covering portions. Excess air is expelled from the space to ambient atmosphere across the waist and sleeve bands to permit extensive upper body movement with relative ease. A pair of overlying positive air pressure barrier is thus provided in an upper body region of the garment to protect the upper body of the wearer from contact with air borne contaminates in the ambient atmosphere.
