Cleveland's new 588 Rotex (RTX) series has been launched three sets of 588 irons and two types of wedges. While the wedges will grab the headline, the three sets of irons are just as exciting. The 588 Altitude iron is all about getting the ball airborne quickly. They feature a forged face for greater feel and a full hollow construction that will offer golfers new to the game, or short on confidence, the ability to get shots airborne from a variety of lies.
