The KING F7 Forged "One Length" irons debut as Cobra�s first ever single-length forged iron set. They're inspired by rising PGA star Bryson DeChambeau. Proper setup includes foot positioning, spine angle and ball position, and many other variables. These variables change as you switch between longer and shorter length clubs. With one setup and one swing you can simplify the entire process. Every player has their favorite club and for many, it's a 7-iron. With Cobra's One Length irons, you will find new confidence in your game, allowing you to play any iron in the bag as if it were your trusty 7-iron. This set comes with 4-iron through pitching wedge. That's 7 total clubs. The gap wedge is also available for an additional charge. Custom shaft and grip options are available. Standard Cobra warranty applies.
