Durable Sunbrella fibers are saturated to the core with color and UV stabilized pigments, ensuring our fabrics won’t fade or become damaged due to the sun’s harsh rays or normal wear. Sunbrella fabrics, unlike ordinary fabrics, are solution-dyed with rich colors that stay brilliant over time no matter the environment.
