Water bags are designed to withstand sub-zero temperatures during the harsh winter weather. Single Tube Water Bags are great for covers with water bag loops so you don't have to worry about them rolling away. Simply fill the bags 1/2 to 3/4 of the way full to allow room for water expansion due to freezing. Lay them tightly on each end of your cover so that no debris can pass through. Roll each bag into the cover at least once to protect them from being popped by animals or storms.
