The Bestway 16′ Oval Fast Set Solar Pool Cover provides the most effective protection to keep bugs, leaves and other debris away when your Oval Fast Set Pool is not being used. The cover is also extremely effective at reducing evaporation. The bubble design enables the cover to absorb heat from the sun and efficiently transfer it to the water. By floating on the water surface, it saves you extra cash on heating and filling up the water. Alternative size covers are also available to suit your Oval Fast Set Pool.
