This is a decent curtain. The panel itself is well made and can easily withstand being outdoors. The reason I am giving 4 stars is that it doesn't "darken" the room as much as anticipated. It does a great job of dimming a room, but  the panel it self lets a decent amount of light through. It is a single fabric layer (vs multiple layers of  fabric). If using outside, it does help to block out harsh rays and helps to create bright shade.
