KING F8 ONE LENGTH

ONE SWING
FOR EVERY SHOT.

With one setup and one swing, you can simplify the entire process and swing every iron with confidence like it's your trusty 7-iron.

SIMPLIFY YOUR GOLF GAME

In a traditional variable length iron set, certain variables including ball position and foot position change as you transition between your longer and shorter irons, causing more room for error. With ONE Length, these variables are eliminated, allowing you to focus less time on your setup and more time on the shot that lies ahead.

WHAT MAKES ONE LENGTH WORK?

One Length Clubs

HEAD CONSTRUCTION

Each ONE Length iron and hybrid club head is re engineered to match 7-iron head weight to promote consistent distance gapping and feel through the set.

SHAFT CONSTRUCTION

Graphite and steel shafts feature adjusted flex profiles to promote higher launch in the long irons and lower, more controlled trajectories in the short irons and wedges.

7-IRON CONFIGURATION

Each club in the set is constructed to match 7-iron length and swing weight specifications to deliver a smooth transition between your long irons and wedges.

F8 ONE LENGTH IRON CONSTRUCTION

LONG IRON
CONSTRUCTION

(4 iron - 6 iron)

Since the long irons have a shorter shaft, we have to add head weight to match 7-iron swing weight. The comparison on the right illustrates where we add weight to the ONE Length 5-iron as an example. This lowers the CG and increases inertia (MOI) to produce increased clubhead speed, launch and distance.

MID IRON
CONSTRUCTION

(7 iron)

The ONE Length 7-iron utilizes the same construction as the variable length 7-iron, illustrated in the image on the right. From the 8-iron to the wedges, we progressively remove more head weight so that each club matches the head weight and swing weight of a 7-iron through the set. Conversely, we progressively add more head weight as we go from the 7-iron to the 4 iron.

One Length Mid Irons

WEDGE
CONSTRUCTION

(GW - LW)

Since the short irons (8i-PW) and wedges (GW-LW) have a longer shaft, we have to remove head weight to match 7-iron swing weight. This is accomplished by using a hollow cavity in the sole, shown in the F8 wedge on the right, which helps raise the CG and reduce the inertia to promote lower launch and more controlled trajectories.

FLIGHTED SHAFT TECHNOLOGY

COBRA® has teamed up with its shaft partners Aldila and True Temper, to engineer unique designs that optimize ONE LengthTM performance. Utilizing flighted 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.

One Length Shafts
LONG IRONS MADE EASY

The long irons feature a lower profile construction, shorter hosels, and wider soles in the 4-6 iron that move the CG lower and deeper. This results is more speed, and higher flying trajectories with more stopping power into greens.

A SHORT GAME YOU CAN BRAG ABOUT

Simplify your short game, and gain more confidence with one set up and one swing. An improved construction delivers lower, more controlled trajectories resulting in more consistency and closer birdie opportunities.

CONSISTENCY
PUT TO THE TEST

LONG IRONS

Many golfers lack consistency and forgiveness with their variable length long irons. ONE Length, as seen in the GEARS test below, can help promote more control and more centered contact on the face, resulting in more consistent distance, launch and feel.

MID IRONS

Improvements in consistency are even noticed in the ONE Length 7-iron compared to the variable length 7-iron. This proves that having one repeatable set up and swing from your long irons to wedges, can translate into improved consistency with the clubs you already feel comfortable with.

SCORING IRONS

The GEARS test below compares the face impact dispersion of the variable length pitching wedge to the ONE Length pitching wedge. Despite the longer shaft length, the ONE Length wedge produces more consistent contact, resulting in more precision on shorter shots.
