Sunbrella® is a solution-dyed acrylic from Glen Raven's Sunbrella Marine Grade collection that is considered the standard cover cloth in the boating industry because of its fantastic color options, high resistance to fading and long lifespan. Sunbrella is a soft, breathable, solution-dyed acrylic that is UV, water and mildew resistant and does not noticeably shrink or stretch. Both sides of this marine fabric are the same, meaning that either side can be exposed to the outside.
