Callaway Big Bertha Irons (Graphite Shaft)

The new Big Bertha Iron set takes forgiveness to new heights by integrating a set of clubs featuring the new i-brids – clubs designed to replace hard-to-hit long irons – and transitioning that set into traditionally shaped irons.

i-brids
The clubs that blend the control & accuracy of irons with the forgiveness, distance & versatility of hybrids. The low, deep centre of gravity (CG) helps get the ball in the air quickly & easily, & the extremely wide sole helps improve turf interaction. As an alternative, traditional-shaped irons are also now available in the long irons. They feature increased offset, a larger effective hitting area & a constant width sole for maximum forgiveness all the way through the set.

• Super Game-improvement Mid & Short Irons
  Designed for the ultimate in forgiveness in their oversize design with an increased offset, a large effective hitting area and a wide sole for exceptional turf interaction.
• Fully Integrated Set Design
  Seamless performance progression throughout the set provides consistent distance separation with optimal trajectories.
• Callaway Golf Core Technologies
  Extreme Notch Weighting redistributes more weight to the perimeter for a higher moment of inertia (MOI) & more stability. VFT Technology maximizes ball speed & perimeter weighting for more distance & forgiveness; S2H2 increases discretionary weight by removing it from the hosel & repositioning it in the perimeter of the clubhead; 360-Degree Undercut Channel maximizes perimeter weighting by moving the CG lower & farther back.
• Modified Tru-Bore Design
  For enhanced feel & performance an advanced version of the original Tru-Bore Design, the polycarbonate tip plug at the end of the shaft dampens vibration.
