Made of water-resistant polyester fabric, the easy-to-clean covers can quickly roll out and over the pillows to protect the pillows from everyday dirt, debris and morning dew. Because of the fade and UV resistance of the slipcovers, you can use the pillows without worrying about the lost of their original appearance or uncomfortableness. Featuring durability, the covers have dense stitchings to tightly cover the supportive fillers to keep their shape for years to come.
