Shade Sails are the ultimate in stylish sun protection. They provide up to 90% UV block while allowing cooling air circulation. Heat and glare are significantly reduced so the shade sails can make you comfortable even on hot days. This sail itself is constructed from a polyester weave material which resists mould, mildew, stain, tear, cracks and fading. You can creatively design your own little shady area in a courtyard, pool, gardens, children's play areas, car spaces, and even entry ways.
