Abstract
Abstract A firefighter garment comprises an outer shell made of a flame-resistant material, a moisture barrier positioned within the shell and an inner thermal barrier layer positioned within the shell and including at least one layer of a mesh fabric. The mesh fabric creates a layer of air between the wearer and the outer shell sufficient to protect the wearer from a high temperature external heat source and yet promotes heat and perspiration vapor transfer from the wearer's body. In a preferred embodiment, the inner thermal barrier layer includes two layers of mesh material, the material having between 8 and 16 holes per inch, quilted to a facecloth material which is located facing the wearer's body.
