This market umbrella brings a breezy spot to your patio or deck while helping you stay out of the sun. The frame is supported by an aluminum pole, providing a foundation for the octagonal canopy. Crafted from weather-resistant olefin fabric, the shade is designed to stand up to the elements throughout the season. A built-in vent at the top promotes airflow to help with stability on breezier days. Opening the umbrella is simple with the manual crank lift. It also features an auto-tilt mechanism that allows you to adjust the angle of the canopy as the sun moves.
