Best Outdoor Fabric Sunbrella performance fabrics are made of 100% solution-dyed acrylic. This unique process makes Sunbrella performance fabrics inherently fade resistant, UV protective, and durable to the core; maintaining color and quality through cleaning, wear, or exposure to outdoor elements. Sunbrella performance fabrics are easy to clean while maintaining the strength and integrity of the fabric. Many performance fabrics are simply regular fabrics with a protective surface finish. Complete performance does not rely on a finish that can wear off. Sunbrella engineers perform at the core of each fiber, including stain-resistant technology.
