Longer, softer, and more amazing than anything you have ever played. There is no question that the Wilson Staff DUO Golf Ball is a true performance double-take. It's the longest ball Wilson has ever made and the softest ball on the market. The Duo is long off the tee with more control thanks to its reduced spin off the driver, and its 40-compression is half the compression of the average leading competitor golf balls. Its true performance value and distinctive feel set it apart from every other distance ball.
