Kinder Industries blanket style sail cover for Freedom 30. Our cover is constructed with marine grade Sunbrella. Our cover is designed to neatly fit the sail when it is flaked. Sunbrella has a 10-year warranty against fading, Sunbrella fabrics hold their vibrant color even with constant exposure to the sun, salt and chlorine of harsh marine environments. All Sunbrella fabrics are mold- and mildew-resistant. Should exposure to dirt, debris and the elements cause mold and mildew to occur, Sunbrella marine canvas can be quickly and easily cleaned with a simple bleach solution. When tough stains such as mold or mildew occur, Sunbrella fabrics can be cleaned with bleach without losing any color. All of the fasteners are made from marine grade 316 stainless steel. Kinder Industries builds a premium product that is made from the best material and meant to last.
