A protective hood jacket adapted to be worn in combination with a protective suit in toxic environments comprises a hood jacket formed of heat-sealable material forming a garment that is hip length and short sleeved. There is a large hump in the rear to accommodate the air cylinder of a self-contained breathing apparatus and to avoid for forward bending. There is a combination closure in the back of the jacket consisting of a metal zipper and a CHLOROPEL zip-loc closure for donning/doffing an air bottle replacement. Vapor leakage is mechanically reduced by two types of seals. The first type encompasses the garment peripheries at the waist and sleeve ends and these seals incorporate cable draw strings and B-lock fasteners allowing for adjustment. The second type constitute internal collars, spaced above the end of the sleeves and waist and around the neck which include elastic webbing providing self-adjustability to fit small, medium and large size personnel. The elastic collar inside the hood, proximate the neck area, is designed to further reduce vapor infiltration to the head area and includes a frontal VELCRO closure which fastens around the BA mask inlet air tube.

A protective garment resistant to hostile environments consisting essentially of: fabric means for defining a hood portion and a jacket portion sealed to each other to receive and protect, respectively, a wearer\s head and torso from the hostile environment, said jacket portion including a pair of sleeves and a lower opening adapted to encircle the wearer\s waist; said fabric means includes a plurality of heat-sealable panels heat-sealed together and said hood contains a visor heat-sealed to said panels forming the hood portion; means for adjustably sealing (1) the lower opening to the wearer\s waist and (2) sleeve openings to the wearer\s arms to resist the entry of toxic materials therethrough into the interior of the jacket portion; said adjustable sealing means includes a waist draw cord and a B-lock fastener formed in the lower opening of the fabric means and a waist collar barrier formed in the lower opening of the fabric means above the waist draw cord, said waist collar barrier including elastic webbing for sealingly hugging the waist area, and hook and pile closure means for snugly securing the webbing in sealing position, and neck collar elastic barrier means located within the jacket portion for sealing contact with the wearer\s neck region to prevent toxic materials from entering the interior of the hood portion through the interior of the jacket portion.
