Callaway XR Single Iron 7 Iron Project X SD Graphite Regular Left Handed 37.0in

Big Bertha B-21 Hybrids are built for distance any way you swing it..
They create fast ball speeds across an expansive area in each model and loft, with our advanced A.I.-designed Flash Face..
We’ve added more offset to help reduce your slice or big miss. This increased offset helps to promote a straighter ball flight for more distance..
Fast ball speed also comes from two internal Jailbreak bars that connect the sole and crown, so the face can take on more of the load at impact..
Features a completely new RCH shaft, designed by Callaway to specifically enhance the Big Bertha offering, with an Active Tip Flag section for easy launch..

The Big Bertha REVA Driver is designed for women to unlock your inner distance..
To help eliminate your slice or big miss, we’ve created our first high launch driver with an ultra-low forward CG for low spin. It’s a new formula for distance to give you a more consistent ball flight, and more tee shots that find the fairway..
The large Big Bertha head is specifically engineered with internal draw bias weighting to help improve your launch angles and promote a straighter, longer ball flight..
We’ve advanced our A.I. designed Flash Face to promote fast ball speeds across a more expansive area..
This face architecture requires extremely strong materials that are lighter and stronger than traditional titanium to promote optimal speed, forgiveness, and spin characteristics..

Big Bertha B-21 is the first Big Bertha Iron with our A.I.-designed Flash Face Cup..
This industry-leading Flash Face Cup is in each club. We’ve created high ball speeds and increased spin robustness with a sophisticated face architecture that’s unique to every loft..
This club profile is engineered to give you more confidence over the ball with noticeably wider soles. For easy launch, lower spin and straighter shots, we’ve added more offset..
We’ve added a significant amount of custom tungsten weighting. So we can deepen the CG in each iron with extraordinary precision, while still maintaining ball speed in the Flash Face Cup..
Our patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds..
