Abstract
A protective garment including an outer shell, a thermal liner and a moisture barrier, in which the thermal liner includes a flame and heat resistant apertured closed-cell foam laminate. The apertured closed-cell foam laminate comprises a layer of apertured closed-cell foam material positioned between and bonded to a substrate of woven aramid material and a substrate of aramid material of a lesser or equal grade. The thermal liner is appreciably non-moisture absorbent and provides high thermal insulation for its weight and thickness in comparison to prior art thermal liners. Accordingly, the overall weight of the garment is minimized, as is the movement-restricting effect of the liner. The non-absorbency of the thermal liner allows the liner to be positioned between the moisture barrier and the outer shell of the garment so that the liner does not restrict flow of perspiration moisture vapor from the wearer to the moisture barrier. The apertures formed in the foam layer promote transport through the liner of moisture vapor from the wearer which passes through the moisture barrier.
