ABSTRACT This invention relates to a multi-layer protective fabric for protective suits used in hazardous or toxic environments. A first layer comprises strips of water and vapour impermeable material, there being a gap between adjacent such strips. A second layer comprises a plurality of strips of a wicking material with each such strip covering the inner surface of a first layer strip, passing through the gap between adjacent strips and covering the outer surface of the adjacent first layer strip. Moisture, such as perspiration will pass via the wicking material through the gaps past the first layer for evaporation and diffusion through a third layer of a liquid impermeable/vapour permeable material which extends over the second layer material covering the outer surfaces of the first layer. rn/rm
