KING F7 ONE Length Irons

The KING F7 ONE LENGTH irons debut as COBRA’s first ever single-length iron set. Inspired by rising PGA star Bryson DeChambeau.

F7 One Length


One Setup One Swing


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 all of your shots

Long irons for more consistent distance

Tighter shot dispersion on approach

Short game accuracy improvement


The KING™ F7 ONE Length™ irons make their debut as COBRA’s first ever single-length iron set. Inspired by our relationship with PGA TOUR Professional, Bryson DeChambeau, The KING F7 ONE utilizes the same TECFLO constructions as the KING F7 along with PWRSHELL™ Faces and Precision Milled Grooves. However, the KING F7 ONE features constant 7-iron lengths throughout the set and each head has been re-engineered for proper geometry to deliver optimized trajectory and distance gapping from long irons to wedges. The end result? A simpler, easier way to play.

Great long irons
Review by Pat - 11/12/2017

Have played one round only with these beauties. A little hard to get used to the shorter irons, but can’t wait to get back out. 7 to 4 really explodes off the head.

Love them

A very good product
Review by Pete G - 12/11/2017

Purchased the standard set 5 to GW and later added the 4 and SW. Not happy with the latter two so they stay in the shed. The 4 has no real advantage in diostance and the SW feels a little flimsy to me. The clubs do take a few games to adjust to but once you get the feel for them, especially the 8 to GW, they are a great club. I don't think the same swing really applies to all clubs as the slight weight variations is evident to me throughout the swing. But I'm not a guru, I play off 12.

With a chronic back problem, the one length golf club maybe the way to go.
Review by Cyborg - 2/09/2017

Well documented, will help me to decide what clubs best suite me.
