Bestway Steel Pro MAX 12' x 30"/3.66m x 76cm Pool SetThe FrameLink System frame is designed to take a large volume of water being moved around as you splash about in it. It is also weatherproof so you can leave it outside even when the weather turns. Its lining is made of a three layer DuraPlus PVC/Polyester sandwich construction that will take a lot of bumps and scratches as you play and splash about. Coming with a 240v a/c filter pump, you can leave the water in when not in use, keeping the water fresh through the season. Where it comes to putting the pool away, no fear of a soggy lawn thanks to the flow control drain valve that can be connected to your hose, allowing you to drain the water to where it's wanted.
