Callaway Big Bertha B21 Irons - 7pc. 4P ST RG (RH)

You’re looking for more distance, and the Big Bertha B21 Irons are here to give it to you. In fact, the legendary Big Bertha shaping is designed with a NEW formula for distance and forgiveness...any way you swing it.

It’s a technology package that delivers more ball speed, higher launch and straighter shots for a new level of confidence that you didn’t think was possible.

With industry-leading Flash Face Cup in each club. High ball speeds and increased spin robustness is created off of every iron in the set with a sophisticated face architecture that’s unique to every loft. Ball speed is further enhanced by the 360 Face Cup that flexes and releases at impact.

This club profile that golfers love 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.

A significant amount of custom tungsten weighting has been added. So the CG is deepended in each iron with extraordinary precision, while still maintaining ball speed in the Flash Face Cup. Now you can get higher launch conditions through the set.

The patented urethane microspheres comprehensively absorb unwanted vibration for exceptional feel, while also maintaining fast ball speeds.
