Tour Edge BackDraft GT+ Steel Iron Set is golf's weapon on the course. This iron set has power, forgiveness and feel. This particular set includes a #3 and #4 hybrid and six irons (5-PW). The hybrids feature a contrasting white color and a low center-of-gravity to make those long approach shots easier. The GT+ irons feature an undercut cavity. These irons give you extra forgiveness due to the channeled cavity. The iron's perimeter weighting allows for a larger sweet spot and greater club head stability.
