Abstract: A firefighter's coat includes (1) a body portion comprised of a flame-resistant shell and a heat-resistant liner, (2) a collar portion comprised of a flame-resistant outer collar part and a fire-resistant inner collar part, the upper edge of the shell being stitched to the lower edge of the outer collar part to provide an outer neckline of the coat, the upper edge of the liner being stitched to the lower edge of the inner collar part to help provide an inner neckline of the coat, and (3) a waterproof interliner which extends from between the shell and the liner of the body portion upwardly between the outer and inner necklines without connection thereto except possibly at their opposite ends, and then between the outer and inner collar parts of the collar portion so as to provide a moisture barrier which prevents water which has seeped through the stitching along the outer neckline from penetrating through the coat to contact the wearer.
