10 ft. Square 2-Tier Aluminum Cantilever 360-Degree Rotation Patio Umbrella with Wheels Base, Beige

2-tier vents allow for full airflow and heat dissipation. Hot air or wind will flow through the multiple vents quickly which can make your market umbrella more stable against windy conditions and cooler underneath. The canopy is made of high-quality 240 gsm fabric which is sun-proof and designed for outdoor use. Moreover, the premium canopy is thick enough for water resistance, fade resistance and UV resistance. The angled aluminum cantilever connects the pole and canopy to form a stable triangular structure, making the umbrella more stable and wind-resistant.
