Suspended energy core
The three-piece construction of Big Bertha irons feature tungsten floating weight that is metal injection molded. The custom tungsten weighting is suspended within urethane microsphere material, pushing the center of gravity deeper while allowing for a faster and thinner face. The result is an ideal combination of feel, sound, easy launch and consistent distance.
Artificial intelligence has been used to design the Flash Face Cup in the Big Bertha Irons that help boost spin robustness and ball speeds. The 360 Face Cup further enhances ball speeds by flexing and releasing on impact.
A streamlined shape improves turf interaction
The shape of Big Bertha has been optimized to improve turf interaction.
Urethane Microspheres for enhanced feel
The use of patented urethane microspheres helps to absorb unwanted vibration to deliver exceptional feel and maintain fast ball speeds.
