The cover contains a thermoplastic non-woven layer containing thermoplastic fibers having a contact angle with water greater than about 70°. The cover contains a UV barrier layer contains containing a UV blocking polymer, having a thickness of between one to three times the diameter of the thermoplastic fibers of the non-woven layer, and containing discontinuities forming microchannels through the layer thickness. The cover also contains an odor mitigation layer containing a UV translucent polymer which transmits at least about 60% of UV(C) energy and anatase titanium dioxide. The odor mitigation layer comprises discontinuities forming microchannels through the layer thickness forms the outer surface of the cover.
