Transform your backyard into a swimming haven with the Bestway APX 365 Above-Ground Pool Set, designed for year-round enjoyment. This round pool combines long-lasting materials and innovative Polar-Shield weather defense technology, making it the first pool of its kind that stays assembled all year long, even through winter. Say goodbye to off-season storage - Polar-Shield protects the liner from outdoor elements, ensuring that the pool can handle cold temperatures and remain in top condition. Built to last, this pool features a galvanized steel frame that resists corrosion. The 100% steel frame is coated in a layer of zinc, providing resistance to rust and protection from the elements. Setting up is simple with the ClickConnect joints, requiring no additional tools. The Tritech liner, made of a 3-layer ultra-durable material, is 15% more resistant to tears, 33% more resistant to stretching, and 83% more resistant to punctures than standard PVC, offering superior durability for summers to come. This pool set also includes a 2,200 GPH sand filter pump and Polysphere filtration balls - a lightweight, washable, and reusable sand alternative that lasts 4 to 6 months with proper care. The set also features a galvanized steel ladder and a pool cover, making it a complete solution for family fun. Made from recyclable, non-toxic materials, the polysphere filtration balls ensure safe water filtration. With a generous size of 22 feet in diameter and 52 inches tall, the Bestway APX 365 is the ultimate above-ground pool, offering durability, ease of use, and year-round performance for making lasting family memories.
