After receiving feedback from some of the most experienced minds at Callaway Golf and, most importantly, women themselves, our engineers designed clubs that react seamlessly with a woman’s unique swing characteristics and feature the latest game-improvement technologies we have to offer.

The Big Bertha 2008 Irons take forgiveness to new heights by integrating a set of clubs featuring the new i-brids™, clubs designed to replace hard-to-hit long irons. The i-brids combine the accuracy & control of irons with the forgiveness & versatility of a hybrid & are the most highly playable hybrid-like irons Callaway Golf could make.<br> <br> In the women's model the 4 through 7 iron is always going to be the i-brid version while the 8 thru lob wedge will be the traditional.<br> <br> On the men's model the 3 through 5 iron comes in both i-brid and traditional. <strong>Please look for the 'i' designation when making your selection.</strong>

<p><strong>The legendary performance of the X-Series in a new iron with even more forgiveness.</strong><br /> The goal of our X-Series Irons has always been lofty: Set the performance standard for the industry. We&rsquo;ve done it again with the X-22 Irons, the best X-Series Irons we&rsquo;ve ever made. The perimeter weighting of the X-22s has been maximized for a moment of inertia (MOI) that&rsquo;s 10 percent higher than their predecessors, meaning you get more forgiveness on off-center strikes. The ideal center of gravity position has been preserved, generating optimal ball-flight trajectories. We&rsquo;ve also incorporated the Modified Tru-Bore design, dampening vibration for enhanced feel. The tour-inspired head shape has a slightly thinner topline and sole with a large sweet spot for improved aesthetics and forgiveness to boost your confidence.</p> <ul> <li><strong>Precision Notch Weighting</strong>: Precisely positions more weight to the perimeter of the iron to create a higher moment of inertia (MOI) for greater forgiveness and stability while maintaining the center of gravity position that produces ideal trajectories and feel.</li> <li><strong>Tour-Inspired Head Shape</strong>: Our engineers took elements designed for Tour players, like a thinner top line and narrower sole, and incorporated them into highly forgiving irons with a higher MOI so they can be played by a wide range of golfers.</li> <li><strong>Modified Tru-Bore</strong>: An advanced version of the original Tru-Bore design, the polycarbonate tip plug at the end of the shaft dampens vibration for enhanced feel and performance.</li> <li><strong>VFT Technology</strong>: VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness; S2H2 increases discretionary weight by removing it from the hosel and repositioning it in the perimeter of the clubhead; 360-Degree Undercut Channel maximizes perimeter weighting by moving the CG lower and farther back in the clubhead, enlarging the hitting area and stabilizing the clubhead for more forgiveness.</li> </ul>

The X Series is about giving serious golfers total performance with enhanced forgiveness for the ultimate in confidence. The new X-20 Irons deliver in every way by offering technology, innovation and playability that will take your game to a new level. Using the Progressive Wall Reduction System, Callaway Golf engineers lowered the center of gravity (CG) 6 percent more than in the X-18 Irons. Progressive Wall Reduction means the CG gets progressively lower throughout the set. The CG is lowest in the long irons, helping you get the ball airborne more easily. With its traditional styling and Callaway Golf core technologies, the X-20 Irons provide the performance and forgiveness to play the game with enhanced confidence.
