Two 16-ft polyester fabric canopy covers work together to restore shade on your existing pergola gazebo, creating a continuous overhead barrier against direct sun while you relax or entertain outdoors. Each 16 x 4 in piece stretches across the frame, and you can slide or reposition the panels to direct shade where you need it most. The weather-resistant polyester with PU coating stands up to repeated outdoor use yet folds for compact storage. Simple attachment points make installation and removal straightforward for cleaning.
