12' Solstice Blue Round Solar Blanket Pool Cover

Significantly reduce heating costs by up to 80% in your pool using this solar blanket pool cover. The superior heat absorption and retention of the cover reduces evaporation, saving water and costly chemicals, as well as extending your swimming season by up to 6 weeks. It's made from a durable polymer material with thousands of tiny sealed air bubbles. They float "bubble side down" on the surface of your pool water when the pool is not in use and allow solar energy to pass through, which is then trapped as retained heat in the pool.
