Abstract
A piece of turnout apparel includes an outer shell of fabric material and a thermal liner which is attached to the outer shell and lines the interior of the shell. The liner includes a first vapor barrier layer of substantially moisture impermeable material adjacent the inner surface of the outer shell, and a second vapor barrier of substantially moisture impermeable material. Between the first and second vapor barrier layers is a layer of fibrous, thermal insulating material. The vapor barrier layers prevent the wetting of the layer of thermal insulating material and thus maintain its thermal insulative characteristics during use.

In a piece of fire fighter's apparel, including an outer shell of fabric material constructed to cover at least a portion of the human body, and a thermal liner attached to said outer shell and lining the interior thereof, the improved thermal liner comprising:
- a first vapor barrier layer of substantially moisture impermeable material adjacent the inner surface of said outer shell,
- a second vapor barrier layer of substantially moisture impermeable material, and
- a layer of fibrous thermal insulating material, positioned between said first and second vapor barrier layers, whereby said first vapor barrier layer prevents wetting of said layer of thermal insulating material by moisture penetrating said outer shell, and said second vapor barrier layer prevents wetting of said layer of thermal insulating material by sweat from a wearer.
