Maximum Vehicle Protection !! Using a unique, patented 3-layer construction sheathing together different materials, Covercraft has created bi-component fibres to manufacture the material for Noah. Outer layer combines softness of polypropylene with weather and ultra-violet resistancy. Inner layer combines polypropylene with a strong nylon core. Middle layer employs a microporous breathable film giving an amazing barrier protection but still enabling moisture vapour and condensation to evaporate away from the car’s finish.
