Sunbrella® solution-dyed performance fabrics are colorfast and colorful with vibrant hues that will last the test of time indoors or out. Sunbrella performance fabrics are made of 100% solution-dyed acrylic. Sunbrella® fibers are saturated with color and UV-stabilized pigments before they’re spun into yarn–meaning the pigment goes all the way through the fibers and the color stays true over time.
