Cover Free's patent pending advanced mono-layer technology offers users the ability to save water and money by decreasing evaporation. A mono-layer (one molecule thick) is formed on the water surface, while surface tension allows it to remain in place or reform during swimming. COVERfree saves you money by reducing water evaporation by up to 85% and water heat loss by up to 70%!
