A wire harness including a number of wires, an outer sheath layer, and an anisotropic fabric positioned between the wires and outer sheath is provided. The anisotropic fabric is formed from combining a number of more rigid, monofilament fill strands and a number of less rigid multifilament warp strands. The fill strands may be formed from a single filament of at least five hundred fifty (550) denier while the warp strands may be formed from a series of polyester threads of at least two hundred (200) denier. The anisotropic layer permits limited rotation of the inner wires relative to the outer sheath when exposed to friction and pressure and is not subjected to significant creep during use.
