Cobra Men's King F7 One Length Irons

One Setup, One Swing, Optimal Performance

Bryson DeChambeau has become a household name for many golf fans in the last few years, which has happened for two primary reasons. First, he compiled one of the best amateur records of any player in the last several decades and has since earned his PGA Tour card. Second, in conjunction with his immense success on the course, he has also become known for playing a set of irons that are all the same length. Upon turning professional, DeChambeau signed with Cobra, which immediately went to work on creating One Length sets of irons for recreational players, including the KING F7 model, which would qualify as a game-improvement offering from Cobra. The idea is that by having irons that are all the same length players are able to to have one setup and utilize the same swing with each iron in their bag, which will make it easier to achieve consistent results. In terms of the KING F7 irons, they all come at a standard 7-iron length of 37.25 inches in both graphite and steel and with the same lie angle of 62.5 degrees. Highlighting the features of the KING F7 One Length irons is their PWRSHELL face, which is thinner and stronger to create a larger sweet spot and faster ball speeds for more distance. Additionally, progressive spin technology promotes less spin for more distance in the longer irons and more spin for increased control in the shorter irons, and perimeter weighting creates max forgiveness on mis-hits. The CG has also been centered in the clubface to improve feel and consistency. The stock shafts for the F7 One Length irons are the Fujikura Pro 63i graphite and the True Temper King F7 steel. The stock grip, meanwhile, is a red, white, and blue Lamkin Crossline.

Ideal For:

Players of all ability levels. In terms of performance, the KING F7 One Length irons have the desired playability of the best game-improvement clubs, most notably high launch, impressive distance, and max forgiveness. That said, these are irons that still have a fairly compact look, clean lines, and soft feel at impact, which might also appeal to better players who value forgiveness above all else.

TGW Customer Review on the Cobra F7 One Length Golf Irons

Watch the exclusive TGW Customer Review on the Cobra F7 One Length Golf Irons.


A stronger, thinner sole and clubface enlarge the sweet spot and combine to produce faster ball speeds from all impact points.

Progressive Spin Technology

V-Grooves are utilized in the longer irons for less spin and more distance, while U-Grooves in the shorter irons create more spin and control.

Zone Weighting

Weight is moved to strategic places along the perimeter of the clubhead to improve forgiveness.

What Players Like You Are Saying...

“Great ball flight, low-piercing ball flight. It was a little weird because I’m used to my longer irons being, of course, longer, (but) it was easy to hit the 4- and 5-iron. I expected the ball to go not as far because it was a shorter length club, but it didn’t.”

Cobra Men's King F7 One Length Irons is rated 4.8 out of 5 by 8.
Rated 3 out of 5 by from Expected More Great looking product. Love the grips. I was expecting more from these clubs. I think it is great that Cobra brought this mainstream and if you are a beginner golfer I would recommend these. I has been playing Taylormade RSI irons and will be going back to them. I feel they are more accurate. All of my shots with the Cobra's are going left of the target. That could be because I ordered with regular shafts. All in I would recommend these but don't think that the one length shaft will save your iron game. Also they seem to hit shorter than the Taylors!

Rated 5 out of 5 by from Great clubs I replaced my Callaway XR's with these irons. I had them fitted and ordered them with the recoil shaft I had in my Callaway's. They feel great and a senior and think they will help me. It takes some getting used to trying to play them all from the same spot in your stance, but all the clubs are the same length and weight and they feel lighter. I may hit the 5 a couple of yards less than my XR's, but it is easy to hit and goes straight. I probably hit the 6 iron through G wedge farther than my XR's. I'm probably 5 to 10 yards farther with the G wedge. I thought I would have problems pitching up close to the green, but I'm not gripping down just changing my swing length and I'm actually pitching better than ever.

Rated 5 out of 5 by from Excellent change I played the M2 Irons and loved them. I bought these clubs and I am very happy. I did not have a 3-6 in my M2 set as I love hybrids. I bought 6-gap in the "one length" and hit the 6 iron with ease. I was not a believer until I hit the irons and now I believe. I have a very high ball flight, which I love, and still hit these irons high. Also bought the Cobra baffler hybrids to replace the M2 hybrids in the set and after taking a while I have learned to hit them well. Very happy

Rated 5 out of 5 by from Terrific concept Very solid club - exactly what you would expect from Cobra. No appreciable change in distance -- ball flight a little higher (was previously playing Mizuno JPX-825). Biggest challenge is the one length -- don't overthink the shot. Have tendency to move ball in stance based on club selection -- don't do that - position where you would a seven iron and swing -- it works! These might not be for everyone but believe they would work well for a lot of golfers.

Rated 5 out of 5 by from One Length I'm all in!!!! I've had mine two months amazing every club feels like my 7 iron as it should. I got fitted 2 flat, KBS shafts and midsize grips. Consistency is there, better ballstriking and distance is good. SImplify your game result better scores. Cobra has a winner here you should check it out.

Rated 5 out of 5 by from Great clubs I've had my clubs now for a month and I'm very pleased with them. The distance and accuracy of these clubs is awesome. I've gained 10 yard on my irons. I also love that I have the same repetitive swing for every club.

Rated 5 out of 5 by from Very Happy Golfer Took these out to the driving range the day after receiving them and was very impressed with them. I actually get more distance and better accuracy than with more old set of Cobra irons.
