This style from our "Watershed" Collection provides many unique features. It is water repellent, so you don"t need to buy an extra liner, and generously sized at 72 by 72. It is mold and allergy resistant, with metal grommets for added support, and has a weighted bottom. Machine washable and fast drying, too. Circle Central features fun green shaded circles on a white background. Many other styles in this collection available here at Amazon!
