The light and strong Exo-Vage design in the Callaway Big Bertha OS Graphite Irons places more weight in strategic locations to increase forgiveness and further expanse the efficiency of the 360-degree cup face design. The next generation 360 Cup Face Technology delivers even faster ball speeds for increased distance. Tungsten loaded standing wave technology lowers the center-of-gravity to promote higher launch angle for longer carry and more ball speed on lower hits in the face.
