The “D” in Wilson’s new D7 irons stands for “distance,” but while the long irons are designed for maximum distance and forgiveness, the short irons and wedges are made for increased feel and control.

“The D7 line is our latest installment of game improvement irons that will give golfers increased distances on the longer irons and precision with the shorter clubs,” said Jon Pergande, Manager, of Wilson Golf Club Innovation.

The long iron soles -- which are wide to assist with turf interaction and launch height -- house three rows of Power Holes. Wilson’s familiar power-hole technology uses urethane-filled holes to increase energy transfer into the golf ball. The difference in these new D7 long irons (4-7) is that Wilson added more holes to enhance that face deflection, thus adding more energy transferred at impact. Additionally, Wilson says the D7 long irons feature Wilson’s thinnest clubface ever. These ball-speed increasing designs make up what Wilson calls RE-AKT technology. Wilson also reports a 10-percent increase in moment of inertia (MOI) compared to their C300 predecessors.

“Our RE-AKT technology and ultra-thin, responsive club face increases ball speeds to help produce maximum distances, while the shorter clubs give golfers a greater feel and more distance control,” said Pergande.

On the other hand, the D7 short irons (8 and 9) have two rows of power holes, the PW and AW have one row of power holes, while the SW has no power holes. The progressive set design tones back those ball-speed increasing technologies as the set works into the scoring clubs, providing the player greater feel and distance control, according to Wilson. Also, Wilson says the shorter irons have optimized weighting.

Made from Cast 17-4 stainless steel, the new Wilson D7 irons are designed to have straighter lines than their predecessors and a cleaner topline, according to the company.

Available on January 17, the Wilson D7 iron sets (5-SW) come stock with Recoil graphite shafts (A, R and S flexes at 65 grams), or KBS Tour 80 steel shafts (R and S flex). Graphite will sell for $699.99, steel will sell for $599.99, and a combo will sell for $799.99.
