Heavy-Duty Space Age Oval Solar Cover Pool Blanket, 15 x 30 Pool

The Heavy-Duty Space Age 15 x 30 Oval Solar Cover Pool Blanket warms up your pool water by up to 12 degrees.

Made of polyethylene material, this solar cover floats bubble side down on the surface of your pool water when the pool is not in use, allowing solar energy to pass through and trap it as retained heat in the pool.

This cover is made of Heavy Duty 8 mil material that helps raise the water temperature by absorbing sunlight during the day and retaining the heat at night, thereby extending the pool season.
