Enjoy your patio this summer under 57 square-feet of shade. Recommended by The Skin Cancer Foundation, the Mirage’s Sunbrella canopy is designed to protect you from 98% of the sun’s damaging rays. An easy-to-use crank opens and tilts the umbrella to your desired position. Vented construction allows air to pass through the fabric creating a comfortable escape from the summer sun.Its 8-rib canopy support system and 1.5-in diameter, anodized-aluminum pole have a strong, powder-coated finish that resists rusting. Fade, mildew, and water-resistant acrylic fabric ensure that this umbrella will withstand the elements year after year. The Mirage umbrella is backed by a 5-year warranty for the Sunbrella acrylic fabric canopy and a 3-year warranty on the pole and structure. The 50-lb base is sold separately.
