-
What It Is
The industry's first electronically enabled set of ONE Length™ irons. Every iron is designed to match 7-iron length and clubhead weighting.
-
Who It's For
5 to 25 handicap golfers with moderate to higher swing speeds seeking a forgiving distance iron with enhanced feel.
-
Why we made it
The KING® F8 ONE Length™ irons have been re-engineered using progressive clubhead constructions and flighted shaft technologies to deliver improved trajectory and feel through the set.
IMPROVED CLUBHEAD DESIGN
Progressive clubhead construction features progressive sole widths and hosel lengths for optimized trajectory and feel from the long irons to the wedges.
FLIGHTED SHAFT TECHNOLOGY
Graphite and steel shafts feature adjusted flex profiles through the set for higher launching long irons and short irons with lower, more controlled trajectories.
7-IRON CONFIGURATION
Each KING® F8 iron is configured to match 7-iron length, head weight and swing weight to promote consistent feel through the set.
ONE LENGTHTM
One Step Further
Flighted Shaft Technology.
COBRA® has teamed up with its shaft partners to engineer unique designs that optimize ONE Length™ performance. Utilizing flighted shaft technologies, the graphite and steel shafts feature adjusted flex profiles that make the long irons play softer and launch higher, and the short irons play stiffer and launch lower.
Long Irons Made Easy
Featuring a lower profile clubhead design with wider soles in the 4-6 irons, the CG is moved lower and deeper to deliver higher launching trajectories. Paired with an optimized E9™ Sweet Zone™, the KING® F8 ONE Length™ long irons are faster and longer, while maintaining the simplicity and accuracy that players find appealing with the ONE Length™ set makeup.
A Short Game You Can Brag About
The key to a better short game is knowing your wedge distances. The KING® F8 ONE Length™ wedges give you more confidence with one setup and one swing, while an improved clubhead construction promotes lower, more controlled trajectories. The result is more consistency, more predictable distances, and closer birdie opportunities.
Re-Engineered
for Consistency
The KING® F8 ONE Length™ irons feature cutting-edge technologies that make them even easier to hit and more consistent than ever before.
Simplify Your Golf Game
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, causing more room for error. 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.
One Swing For Every Shot
In a traditional iron set, certain variables of the swing change as you switch between your longer and shorter irons, causing more room for error. With one setup and one swing, you can simplify the entire process and swing every iron in the bag with confidence like it's your trusty 7-iron.
Better Distance Gapping
Studying real-world yardage gaps using Arccos data, many players have distance overlap with their variable-length long irons. ONE Length™ long irons provide more confidence at address, promoting more consistent ball striking and carry distances.
Tighter Shot Dispersion
Having a more comfortable, repeatable swing that is shared between your long irons and short irons promotes more consistent contact. The result is more greens-in-regulation, tighter approach shots and more birdie opportunities.
More Accurate Short Game
If there are weak points in your short game, you are not alone. The KING® F8 ONE Length™ wedges provide a seamless transition from your long and mid irons allowing you to set up to every shot with confidence and attack the pin with more consistency.
