The Noah barrier fabric resists moisture, but it breathes to allow trapped moisture, seam seepage or condensation to evaporate easily. The unique construction process (patent pending) gives coverage with maximum all-weather protection. . . Highly water resistant, dust resistant, UV resistant and breathable to ensure moisture and/or heat does not remain under the cover. Made in the USA by Kimberly-Clark, the fabric weighs only 4. 2.126 g/m². Yd. so it is easy to handle and fold. High-tech bonded 4-layer composite uses two-component side-by-side technology for double-spunbond outer layers, a film barrier and a soft two-component spunbond inner layer.
