A 10-ft square canopy with three stacked vents at the crown, aimed at patios that catch afternoon wind. Each vent tier lets hot air climb out and takes the lift out of a gust before it reaches the fabric. Winding the crank raises the shade, and a button on the upper pole steps the angle over as the sun travels west. Eight thickened ribs sit in reinforced pockets that hold the polyester taut instead of letting it sag between them, and the pole sections push together by hand with no tools involved. A fixing strap binds the closed umbrella for storage.
