Eight fiberglass ribs flex rather than fight a gust, giving this 10-foot scalloped umbrella an edge over rigid frames on a windy deck. PA-coated polyester fabric resists wear, water and sun, and the ruffled edge sways gently in a breeze. Push-button tilt tracks the sun through the afternoon, and a smooth crank opens and closes the canopy. An air vent aids circulation, a three-level safety latch keeps the canopy from sliding down, and a snap-in locking button joins the two poles. A hook and loop strap secures the folded canopy. Overall size is 9.4 by 8.2 feet with a 10-foot outer canopy and 6.5-foot rim height, 14 pounds.
