Sunbrella is a woven synthetic canvas fabric from Glen Raven Mills, Inc. that is made of 100% solution dyed acrylic fiber by Du Pont, which has the highest resistance to deterioration from ultra-violet sun rays. Because its rich color is an integral part of the fiber it can't be washed away or bleached out by the sun, rain or chlorine. Rest assured your boat cover will look fabulous nautical mile after mile.
Because Sunbrella is woven for breathability, it doesn't trap heat and moisture, eliminating mildew. As a result, Sunbrella stays fresh and beautiful season after season.
In addition to longevity and durability, Sunbrella fabric also provides protection from the sun so you can enjoy long hours on the water. Sunbrella fabrics carry the Skin Cancer Foundation's Seal of Recommendation, giving your family and friends the extra assurance they need. (Learn more about preventing skin cancer)
In extreme southern climes, you can expect Sunbrella tops and covers to give 5-8 years of good service even when exposed to the elements every day of the year. In northern climes, Sunbrella can last as long as 15-20 years and still perform adequately.
Sunbrella is not a waterproof fabric, it is water resistant. The water resistance wears off eventually and the fabric must be treated to regain it's original water resistant barrier. Use 303 Fabric Guard for best results.
You will find that Sunbrella fabric tends to grow a bit after it's first exposure to outdoor weather, in some cases expanding as much as 2% over the course of a year. As Sunbrella further ages it shrinks back to it's original size.
