Abstract

A firefighter garment having a low friction liner system which includes an outer shell made of an abrasion resistant material, a moisture barrier layer made of a water-resistant material, a thermal barrier layer and a layer of material having flame, heat and high-lubricity properties positioned within the outer shell. In one embodiment, the high-lubricity layer is composed of a fire resistant filament yarn and is attached to the inside face of the thermal liner; that is, the face positioned next to the clothing of a wearer of the garment. In another embodiment, the layer of high-lubricity material is positioned to form a substrate for the moisture barrier and is located between the moisture barrier and outer shell. A garment having two layers of high-lubricity material, one forming an inside face of the thermal liner and the other forming an interface between the moisture barrier and outer shell, is also preferable. Alternately, the high-lubricity material is in the form of patches positioned at areas of high movement and friction on the garment, such as the shoulders and elbows of a coat, and the knees of a pant. All of the aforementioned embodiments reduced the friction between the layers of the garment, and between the garment and the wearer, thereby reducing the amount of energy expended by wearer of the garment while moving. This reduction of energy reduces the amount of stress imposed by the garment on a wearer.
