Water-resistant and breathable, made of high performance Marine Grade Sunbrella Fabric. Rich color is an integral part of the fabric components and can't be washed away or bleached out. Fabric is woven for breathability, so it doesn't trap heat and moisture, eliminating mildew on the fire pit surface for a cleaner look. Fabric also provides protection from the sun so you can enjoy the natural concrete colors of the fire pit longer. As a result the fire pits stay fresh and beautiful through the winter season reducing the maintenance required at the start of each season.
