GoSports Gagagon, 15 ft
Steel poles, polyester mesh, rubber feet that hold on a gym floor as well as on grass. Rated for 6 to 12 players, which is where most groups actually land. Two 8.5 inch balls, a pump and a carry case in the box. The frame goes up in minutes; the velcro along the base is what takes the time.
Worth knowing: 35 lb, heavier than any inflatable of the same diameter. That weight is also why it stays put once kids start hitting the walls.
