Abstract
Abstract A protective garment, jacket and/or pants, made of a fabric unit which includes an outer shell and an inner shell with a liner therebetween, these being secured together at edges thereof. The outer and inner shells are formed of light, non-moisture-absorbent fabric capable of withstanding high temperatures, and said liner is formed of relatively soft and heat resistant fabric and is thick enough to give the fabric unit a predetermined thickness and to act as a spacer to allow for air insulation and circulation.
