Pool Mate 1-3809-20-BLK-05 Extra Resistente 20 Calibro 8 Piedi Nero Acqua Invernale

These water bags include leak-proof valves that are easy to fill with a garden hose. Only fill the water bag half-way, this prevents ice from expanding and splitting your water bag. Pool Mate water bags feature a dual-chamber design, preventing the tube from rolling into your pool during the winter.
