Noah Barrier Covers are manufactured from a three-layered fabric which offers Exceptional Vehicle Protection. Snow, sun, rain, dew, dust, dirt, industrial pollutants, tree sap, bird droppings and other environmental hazards including acid rain are all kept away from your vehicle's finish. By sheathing together different materials, Kimberley-Clark has created bi-component fibres. The outer layer combines the softness of polypropylene with the weather and ultra-violet resistance of polyethylene. The inner layer combines polypropylene with a strong nylon core. The middle layer employs a micro-porous Breathable film which gives the fabric its amazing Barrier Protection but still enables moisture vapour or any condensation to evaporate away from the car's finish. This extraordinary new concept makes the Noah Barrier Cover exceptionally Soft for the protection of delicate paintwork but Strong enough to resist rips and tears and guard against knocks and scratches. Hand Washable, the cover is Light Weight and Compact for easy storage and daily use. Even if folded and stored wet, the material will not rot or support the growth of mildew.
