The Dual Identity is 2 shelters in one. When you need shade set up the gazebo and when the bugs are harassing you attach the screen sides to the inside of the frame. Versatility is the biggest plus to this shelter. Free standing and easy to assemble as well as a large amount of interior space set this shelter apart from others in its class. 2 large doors make entry simple. The Dual Identity is large enough for several chairs or a picnic table.
