Shade your outdoor seating area with the Shanghai-style Shade Trends The Breeze 8.5 ft. Oversized Wind Vent Umbrella. Large enough to be effective, this vented umbrella allows heat to escape. While most umbrellas have just 12 ribs, this one has 24 fiberglass ribs that can move with the wind, avoiding breakage. The crank lift design is easy to manage, and a collar system allows you to adjust the tilt. Solution-dyed acrylic fabric allows the two-tone canopy to beautifully resist mildew, fading, and all weather conditions. Ensure that your umbrella is fully dry before closing it.
