Water bags are the best way to keep your pool cover secure all winter long. The water bags are manufactured from quality heavy gauge vinyl that has been treated with UV inhibitors and anti-bacterial and anti-fungus additives. They are designed to withstand sub-zero temperatures and we recommend that you use the single tubes for covers with water bag loops.

When using water bags be sure to only fill water bags 1/2 to 3/4 full to allow room for expansion due to freezing.
