The new Warbird Plus Golf Ball becomes a member of the HEX family. For the first time on a Warbird, Callaway ditched the dimples and incorporated HEX aerodynamics. When you throw in the new high powered core, it becomes the longest Warbird Callaway's ever made. The core also has better feel off the clubface. The durable ionomer cover provides long-lasting playability and also helps increase the deep distance this ball generates.
