Introducing, new in 2018, the worlds best arena polo ball. Redesigned with a balanced bladder that for the first time allows the ball to travel straight when hit long and hard. A 30 grms bladder perfectly balanced between the air receptacle and the bladder allows for straight flight no matter how strong or hard the hit. Combine that with a 32 panel balanced outer and you have a polo arena ball that has less leakage, that holds the air longer, and travels straight in flight. The total ball weights 150 grams and is inflated to 30 to 35 psi. This makes a superior ball for better players, to play better or for tournaments. Once you use these PoloGear performance arena polo balls all else is inferior.
