Keep Your Above Ground Pool's Cover in Place Throughout the Winter

These wall bags for above-ground pools are made of heavy-duty vinyl and designed with a leak-proof valve and two reinforced holes to hold them in place at the pool's edge. For use, fill them partially full of water to allow room for expansion if they freeze in low temperatures, and secure them on the winter cover at the pool wall. These water bags will stay in place even during windy weather, holding your cover down and keeping your pool clean and protected.
