Playing table tennis with friends can be lots of fun. You can even get a table tennis robot to give you lots of practice. If you plan to play table tennis outdoors, you should think about getting an all-weather ping pong table. The Foldaway All Weather Tennis Table Court has you covered. Its aluminum composite playing surface does not absorb moisture, so it can survive rainy weather. The table also has all-weather net and posts.
This table has a heavy-duty steel frame with four 1 1/2″-diameter steel legs, rolling on four 4″ casters, Its corners have molded plastic pads. You can close your table to store it easily. Not cheap though.
