Double-sided patio umbrella spans a 13 x 7ft canopy to cover a larger outdoor seating area while the 12.4 x 6.5ft inner span helps concentrate shade where you need it most. The polyester fabric canopy is sun-protective, tear-resistant and drizzle-resistant for lasting use, supported by 12 reinforced ribs for balanced stability. Three top air vents help relieve wind pressure and improve airflow. A crank lift opens the umbrella smoothly, while a fixing latch helps keep the canopy securely open during use. 108 solar-powered LED lights with 8 static colors, 4 dynamic modes and optional Type-C charging provide color-changing illumination for evening patios and gatherings.
