CALLAWAY BIG BERTHA GRAPHITE IRONS 4-SW
The Callaway Big Bertha Iron could make you up to two clubs longer. You might think Callaway is joking, but they're not. This iron is that long. The built-in 360 Face Cup technology is the real deal, bringing incredible distance that you've never seen before in an iron. Welcome to the new generation of long!
360 Face Cup:
If you want to know what makes "two clubs longer" distance possible, this is it. The 360 Face Cup technology generates impressive ball speed across the face through a VFT and with maximum CT.
Internal Standing Wave:
The center of gravity (CG) is low and forgiving. And by doing this, Callaway offers up the full package of high moment of inertia (MOI) for maximum forgiveness and ball speed.
The name is kind of a giveaway, isn't it? The hollow body construction is all about maximum performance and the type of ball speed you see off the center of the face. You'll get that all over the face now.
Premium Shaft Option:
The True Temper Speed Step 80 offers distance and control for maximum performance.
