This market umbrella is a welcome addition to any back patio that could use some extra shade. It's crafted from powder-coated aluminum, which is resistant to rust, corrosion, chipping, and peeling. The metal umbrella frame and six support ribs are wrapped in weather-resistant UPF98 Sunbrella fabric, so it's sure to stand up to UV rays or rainstorms rolling through. And we love how the vented design and an auto-tilt function are easy to adjust, thanks to the handy crank lift.
