The Cleveland HB3 Iron Set is Cleveland Golf's third generation of HiBORE Irons. They are lighter, faster and longer than any of Cleveland's previous hybrid iron sets. Advanced internal weighting design removes weight from the crown and sole recesses for internal discretionary weight placement and a 12% deeper face-to-center-of-gravity depth when compared to Cleveland’s HiBore XLi irons. That just means the center of gravity is lower and farther back from the clubface to maximize power and distance. The recessed sections of the HB3’s sole help to reduce drag as well as improve turf interaction so your swing speeds will be faster and you’ll get more solid hits on less-than-ideal lies. The entire set features seamless transitions from one head shape and size to the next as well as full hollow construction throughout for consistently easy-to-hit performance.
