Every morning the sun shines brightly into my bedroom making it impossible to sleep in on the weekends. These curtains fixed that problem! Not only does it keep the room nice and dark so I can sleep until I’m ready to get up, it also keeps the room cool during the summer which my AC appreciates. The material is pretty thick and seems well made. It feel more like a tarp than a curtain but I can live with that for how well it blocks the light.
