Thicker 6 Pack Pool Cover Water Bags for 10FT Inground Swimming Pool Winter Cover

About this item

• 0.7MM Thickness: Compared to thinner, single-layer PVC bags, the 3-layer construction provides better structural integrity. It holds its shape more consistently when filled with water, which ensures better ground coverage, preventing the tube from shifting or collapsing. This results in better performance in holding pool covers down
• Hot Air Welding Process: Can keep the composition of materials consistent, making the welding joint more fused and sturdy, greatly reducing the risk of cracking, and enhance the water bag's load-bearing capacity to ensure superior air-tightness and pressure resistance；and the wide seam design of the pool bags for winter reduces the likelihood of cracking and leaking to around 2% 
• Leak-Proof Screw-On Caps: Equipped with screw-on caps instead of tricky snap-on styles, these pool tubes for winterizing are designed for user convenience. the screw cap includes a rubber seal, preventing leaks and making setup easier and more secure compared to other options on the market with snap-on or loose-fitting caps
• Versatile Design: Simplifying the winterization of your pool is easy with our versatile single-tube water bags. Their flexible design conforms seamlessly to curves, making them perfect for pools of any shape, whether rectangular or rounded. We recommend filling the water bags to 1/2 - 3/4 of their capacity to accommodate water expansion as it freezes during winter months.
• Flexible Design: Winterizing your pool is hassle-free with our flexible single-tube water bags. Their adaptable structure easily bends around curves, making them ideal for both rectangular and rounded pools; and please fill water bags 1/2 - 3/4 full to allow extra room for water freezing expansion during the cold seasons
