Help protect your umbrella with this marine grade sunbrella cover. Sunbrella is 100% solution-dyed acrylic fabric. Sunbrella umbrella covers withstand sun, wind and rain while remaining beautiful for years. The secret to the lasting color is found in the solution-dying process which locks colors into the acrylic fibers, so they can't wash out or fade. Sunbrella fabric is not waterproof; it is water repellant. This means that during the finishing process a water repellant finish is applied to the fabric of the Sunbrella umbrella cover. Normal wear and usage will reduce the effectiveness of this finish as will cleaning the fabric. Sunbrella fabrics used in our sunbrella umbrella covers, if kept clean, will not mildew. An inherent characteristic of acrylic fiber is that it will not support the growth of mildew, as a natural fiber will. Sunbrella fabrics have been tested and proven to provide up to 98% UV protection from the harmful effects of the sun depending on depth of color. Whites and lighter colored fabrics provide less protection than darker fabrics which have more depth of color. This protective factor is inherent to the product and will not be reduced by usage and/or fabric exposure to the sun. Marine grade sunbrella fabric has a five year warranty against fading.
