Fusion Technology – Callaway Golf’s innovative weight distribution technology – is pushed to the limit in the new Big Bertha Fusion Irons. This radical design delivers everything you would expect from Callaway Golf. The new Big Bertha Fusion Irons play longer, offer unmatched performance and playability, and look great! Three distinct materials – a dense Tunite alloy cradle, lightweight 6-4 titanium face, and special vibration-dampening TPU SenSert – are married together in our most technologically advanced irons ever manufactured.

• The most un-traditional traditional-looking irons you’ll ever play
• 77% of the clubhead weight is positioned around the perimeter of the clubhead, creating a high Moment of Inertia
• New head shape provides confidence at address for players of all ability levels
• Tunite alloy cradle for unprecedented perimeter weighting
• Lightweight titanium face for larger hitting area and increased ball speed.
