Big Bertha Hybrid

The First Hybrid To Combine Jailbreak Technology and Adjustability

The new Big Bertha Hybrids are the first hybrids ever to combine innovative Jailbreak Technology with adjustability for fast ball speeds, long distance, and easy launch.

Long Distance and Fast Ball Speeds From Jailbreak Technology

Our revolutionary Jailbreak Technology incorporates two internal bars that stiffen the body, placing more impact load on the face to promote fast ball speed and long distance.

Fast Ball Speeds From an Ultra-Thin Face and Hyper Speed Face Cup

The ultra-thin, Carpenter 455 steel face is extremely fast. That, combined with our Hyper Speed Face Cup, promotes fast speed across the face to promote long distance on center hits and off-center hits.

Easy Launch From a New OptiFit Hosel

To combine Jailbreak and adjustability for the first time in a hybrid we developed an entirely new hosel system that's shorter and lighter. It allows us to save weight that's repositioned to optimize the Center of Gravity for easy launch and high, long-carrying flight.

Easy to Hit From New Progressive Shaping

Big Bertha features a progressive head shape that's both forgiving and appealing, and packed with high MOI technology.

Feel and Control From New Premium Shafts

Available in premium Recoil ESX and ZT9 Shafts to provide excellent feel and control.

Big Bertha Irons

Our Easiest To Launch Distance Iron

The new Big Bertha has transformed the super game-improvement iron category. It's our easiest to launch distance iron, and it's led by our groundbreaking Suspended Energy Core.

Easy Launch, Distance, and Incredible Sound and Feel From the Suspended Energy Core

The Suspended Energy Core is the engine of the new Big Bertha irons. This revolutionary new construction suspends the MIMdTungsten weight using our proprietary urethane microspheres. It's designed to deliver easy launch; long consistent distance; and incredible sound and feel.

Long, Consistent Distance From Our 360 Face Cup

Our innovative 360 Face Cup employs a flexible rim around the face that flexes and releases at impact to increase ball speed. And by using the high launch angles generated by the Suspended Energy Core, we're able to make our thinnest face cup for increased speeds that promote longer distance.

Premium Design

Big Bertha has an unforgettable look with its clean Smoked PVD Finish. Available with new Recoil ESX, Recoil ZT9, and KBS Max 90 shafts.

June 4, 2018
I had been playing an older version of the Big Bertha irons for two years and as a senior golfer (@74), hold a USGA Handicap Index of 4.2. While par is 72 from all tees, the course rating is 66 from the seniors'. I frequently shoot par and below and beat my age. My current goal is to break 70 and reduce my index to ZERO! My plan is to hit more fairways and greens, get the ball closer to the hole and make more putts. I've got the latest equipment, COBRA F-8 Driver and 3/4 wood, Callaway hybrids and irons, four Callaway wedges and a new O Works RED, MARKSMAN Putter. I was able to buy this equipment with the Trade-In-Store Credit program!

Solid & Consistent!
I've had these clubs for a little over a month now and played 5 rounds on them. I am very pleased with the way they feel and the way the ball comes off the face. The ball flight is very consistent, higher trajectory than I'm used to but flies very true, even on off center hits. I've gained a few yards between clubs with these so that's taking some getting used to but I'll adjust in time. I researched a lot of clubs and tried quite a few before deciding on these. I'm an 8 handicap and hit the ball consistently. These irons are considered super game improving but they will even help the better players. You can't go wrong with them.
