Help warm and protect your pool with this 12 mil solar pool cover designed to retain heat and reduce debris. Thousands of small bubbles capture sunlight to help raise water temperature over time, while also helping reduce heat loss on cooler nights. Placed bubble side down, the cover helps keep leaves, dust, and other debris out of the water and can help reduce water and chemical evaporation, which supports easier pool maintenance. Made from PE material, this pool blanket is designed for outdoor use and can be trimmed with scissors to better fit many pool shapes. When the day is done, fold the cover and store it in the included carrying bag with handles for space saving storage and easier transport.
