It also comes with the centerpiece #4, #5 and #6 A3OS Boxer hybrids, which feature the breakthrough Boxer Technology shaping for a category-leading moment of inertia (MOI). Living up to its name, Boxer Technology creates a boxier clubhead design, which moves more weight to the rear and perimeter of the clubhead and helps to increase the MOI for greater forgiveness, translating into extreme forgiveness, increased ball speed for greater distance, and more spin resulting in a high-launch trajectory and more carry distance.

The A3OS Boxer hybrids have a category-leading MOI of 3350, which is between 30 and 70 percent higher than other leading hybrids. Other features include a low and deep center of gravity for easy to hit shots, maraging steel alloy pull-face with milled grooves for a more consistent performance, and a cambered sole designed to cut through turf interference.

The set also includes:

• 460cc titanium driver: The largest size driver allowed by the USGA for maximum distance and power.
• #3 and #5 Fairway Woods: Patented low profile club face lowers the center of gravity and provides more effective hitting area for easy to hit shots
• #7, #8 and #9 hybrid irons: Three iron-like hybrids move the weight low and back and provide better launch angles and consistency with approach shots. They transition the launch conditions between the Boxer hybrids and the wedges for consistent gapping while having the benefits of hybrid technology.
• PW, GW and SW cavity back irons: Precisely positioned center of gravity and a large sweetspot makes these clubs the easiest-to-hit short irons offered and allow you to hit your shots with pinpoint accuracy.
• Contemporary mallet style putter with heel toe weighting

Golf Talk
Moment of Inertia--This is the term applied to a clubhead's resistance to twisting when the ball is struck, and it can be expressed as a numerical measurement. A clubhead with a higher moment of inertia (or MOI) has greater resistance to twisting and offers more forgiveness on off-center hits (i.e., will fly straighter). The size and weighting properties of a clubhead can be manipulated to add a greater MOI.
