At Callaway Golf, the new products just keep coming. The last few months have seen the debut of sticks ranging from Mack Daddy 2 wedges to FT Optiforce drivers to Apex irons.
Callaway's latest revelation is the X2 Hot line of clubs. The line's two complete sets – a Standard and a Pro version – of drivers, fairway woods, hybrids and irons, are all developed to be longer and faster as well as more forgiving for a wide variety of golfers.
''With the X2 Hot line, we challenged ourselves to reinvent each product to meaningfully improve distance, speed and forgiveness across every category,'' said Callaway Senior Vice President of Research and Development Alan Hocknell. ''We worked hard for every extra gram of discretionary weight, every thousandth of an inch of metal, to increase ball speed and overall distance while improving total performance, especially on off-center impact.''

The X2 Hot drivers debut the company's Hyper Speed Face technology, which creates a large sweet spot positioned where golfers are most likely to make contact with the ball. In addition, players can independently adjust the drivers' loft and lie with Callaway's Advanced Optifit Hosel. The loft can be decreased by 1 degree or increased by up to 2 degrees to help optimize the launch angle and backspin, while the lie angle also can be adjusted between Neutral and Draw. A total of eight settings are available to adjust trajectory and shot shape.
The standard version contains a 460cc head, offers 9-, 10.5- and 13.5-degree lofts, and comes stock with an Aldila Tour Blue shaft. The Pro version, available in an 8.5-degree offering, is 440cc, features a lower and more neutral center of gravity, and includes a 7-gram external weight and a stock Aldila Tour Green shaft. Both models carry a suggested retail price of $349.99.
In the X2 Hot fairway woods, Callaway is introducing Hyper Speed Face Cup technology, which incorporates a thinner face for added ball speed, particularly on impacts low on the face. This new technology, Callaway says, adds 1.4 mpg of ball speed over the 455 carpenter steel face cup utilized in last year's fairway clubs. The company also improved the Internal Standing Wave, a weighting system that positions the center of gravity close to the face for the best possible performance for impacts all over the face.
The options in the X2 Hot Fairway Wood expand the distance and versatility choices for various player types and playing conditions. This includes new versions of the Deep Fairway Woods, which made headlines when Phil Mickelson used one to birdie the par-5 17th hole at the British Open last summer en route to his Claret Jug.
Options include a Standard 3-, 4-, 5-, 7-, 9- and 11-wood and a 13.5-, 15-, 17- and 19-degree loft in the Pro model. In addition, Callaway will add to its Deep series with an X2 Hot Pro 2Deep, 3Deep and 5Deep offering. Stocks shafts are the same as the driver. These clubs all carry a suggested retail price of $229.99.

Callaway is offering a 3-, 4-, 5- and 6-Hybrid in the Standard model and a 16-, 18-, 20- and 23-degree hybrid in the Pro edition. They feature the same stock shafts as the other woods, and carry a suggested retail price of $199.99 per club.
The Pro model has a thinner face and a uniquely designed stabilizing arch that moves the weight low and central to retain the Standard model's high ball speed and distance advantages. However, it features a more compact shape and does without the undercut cavity. It also has a greater progression in offset and Center of Gravity height, which help retain some forgiveness in the longer irons while making the short irons more controllable.
In the Standard model, the stock steel shaft is a True Temper Speed Step 85, and the suggested retail price is $799.99. The stock graphite shaft is a lighter-weight offering, and those clubs retail for $899.99. In the Pro model, the standard steel shaft is the Project X 95 Flighted shaft, and the new product introduction retail price is $899.99.
