Nike SQ Machspeed 8-Piece Men's Iron Set (4-AW, 2011 Model) for $297.49

The Nike SQ Machspeed iron set combines a radical new design with a hot, thin alloy face, making these the fastest Nike irons ever produced. SQ Machspeed irons are made using a unique off-the-face weld construction. This design creates a hot center area on the stainless alloy face, but also expands the hotness to lower on the face where the ball is more likely to be in contact.
