Designed for distance seekers who want to see maximum flight, the Callaway (R) HEX Warbird (R) golf balls are an ideal choice. The larger, softer core results in faster ball speeds for maximum distance and the thinner cover enhances feel without sacrificing speed or distance. The proprietary surface pattern is re-engineered to produce even better low speed lift and distance. Each Ionomer-made ball leaves plenty of room for an imprint! 7-1/2"w x 5-1/2"h x 1-3/4"d.
