Abstract: A firefighter's garments include a coat and trousers. Each of these garments has an outer shell and an inner liner. The inner liner has a section secured thereto which is attached to the outer shell and which serves as an important part of the outer shell. Therefore, when the inner liner is removed from the garment, the garment is not readily usable by a firefighter. In one embodiment of the invention the section which is secured to the inner liner serves as an element for attaching together two separable parts of the front portion of the coat or trousers. Therefore, when the inner liner is removed from the outer shell, the front parts of the garment cannot be attached together and the garment cannot be used by a firefighter. In another embodiment of the invention, the inner liner is attached to the cuff portions of the trousers and to the cuff portions of the coat. The cuff portions may be significant parts of the garment.
