The Dual Runner Sole design promotes better turf interaction for more consistently solid contact. The BB OS Hybrid club is made for any player who wants a hybrid thats super easy to launch high and long. Womens and Senior models are engineered with slightly lighter heads and more loft to promote faster ball speed and higher launch angle to make it easy to get the ball in the air.
