TaylorMade's 2017 M2 irons give golfers complete performance with low center of gravity in additiona to Speed Pocket technology, face slots, and Geocoustic engineering. It is TaylorMade's most technologically advanced distance iron ever made! M2 irons incorporate a new thin-wall Speed Pocket, designed to increase face flexibility and protect ball speed on strikes below face-center while also increasing launch angle and ball speed. It's why you'll hit these irons longer than anything you've tried previously. Further improvements include a new thinner, wider, six-sided fluted hosel that saves 5 grams (compared to 3 in the original M2 iron) allowing for the repositioning of 2 grams of discretionary weight lower in the clubhead. Similar to the M2 metalwoods, the new M2 irons were designed employing TaylorMade�s new Geocoustic engineering techniques; acoustics tuned through geometry to create ideal frequencies for pleasing sound & feel. The sand wedge and lob wedge can be special ordered for an additional charge. Nearly endless customization of the M2 irons is also available. Standard TaylorMade warranty applies.
