- Exo-Cage Technology
- Progressive Centre of Gravity
- 12 Months Warranty & True Temper Speed Step 80 Steel Shafts
Forgiveness & Ball Speed
The light-and-strong design of the Exo-Cage allows more weight to be positioned in strategic locations to increase forgiveness. Combined with next generation 360 Face Cup technology to elevate the club face COR closer to the USGA limit to produce faster ball speed and greater distance.
The set features a progressive centre of gravity with Tungsten-Loaded Standing Wave technology which produces more ball speed, from the lowest to the highest irons, the COG position has been located low in the club head for higher launch and increased carry distance in the low irons, and increased control in the short-irons.
