ABSTRACT:
Two sheets of reflective plastic film included in the construction of a fiber-insulated thermal garment mitigate radiated heat loss while retaining the conventional insulating properties of fibers. A layer of porous matted fibers separates the two layers of reflective sheets, holding them apart and allowing a free passage of air between. The plastic sheets are provided with venting holes which allow the garment to "breathe" and prevent moisture accumulation. The venting holes in opposing plastic sheets do not align but rather are offset, forcing warm air passing through the garment to follow a zigzag route. The plastic sheets are further provided with a flat black finish on their outer-facing surfaces in order that the inside sheet may recapture radiated heat from escaping warm air and the outside sheet may absorb any ambient radiated heat, such as sunlight. Two layers of breathable fabric give the insulation assemblage structural strength, the inside fabric layer being a lightweight material and the outside layer heavier and wind resistant.
