Men's Right-Hand Cobra King F7 One Length

Standard Lie Angle

Description

The Cobra King F7 One Length iron set is Cobra’s first ever single length iron set with constant 7-iron lengths to deliver optimized trajectory and distance gapping from long irons to wedges. The set features PWRSHELL Technology for a thinner, stronger face and sole structure to provide the largest Sweet Zone ever with higher ball speeds and explosive distance. The CG is lower and centered on each club for increased precision. The set also features TecFlo Construction; a full hollow design with face insert in the 3-5 irons, a half hollow design in the 6-7 irons, a cavity back design in the 8-PW and a specialty wedge design in the GW and SW. The “Versatile” grind design on the wedges feature toe, heel, and trailing edge relief while the nickel chrome plating on all irons provide enhanced durability and an appealing look at address.

What I've always been looking for

Review by Lawrence B, 4 years ago.

“I've always dreamed of a set of irons that would simplify the game. From the start of golf, the idea of same length irons made sense to me, but until 2017, the option wasn't readily available. Budget is issue for me, so when I saw a used set in good condition for a cheap price I made the jump, and traded in my irons for cobra one length. The set happened to be graphite shaft, mamiya recoils, F3 flex which I found out later was regular not stiff.. which I have to say are great for graphite shafts and performed well. I tested them on hitting board, and got them all bent up 2 degress, and I choked down on them throughout the set to get them to act a little stiffer. Despite being regular flex they performed the best of any iron I've ever used, and did what they were intended to do.. made the iron game easier. After playing the irons for several months I decided to reshaft them with Dynamic Gold s300 stiff flex. Also, since I had realized that I could choke down a half inch on all the clubs, and still get great results, I decided to get the irons all in 8 iron length. Wow... totally awesome results. DO NOT BE AFRAID to get a set in 8 iron length, it makes the short irons easier to hit, as well as the long irons, and it won't affect the distances or the gapping.. it will just make things easier. Btw if you want the five or six iron to get higher just play them up in the stance a little bit like you would traditional longer irons, they'll still be WAY easier to hit and control than traditional clubs. Anyways.. if the idea suits you, go for it.. once you get the feel of this one length set, you'll realize there's no need for variable length. However.. I do play traditional length sand and lob wedge, but I wouldn't be scared at all to use the one length I just don't want to put out the money.”

4 - 5 - 6 Cobra King F7 One Length Irons

Review by Robert T, 4 years ago.

“This review is for the Cobra King F7 4-5-6 One Length Irons ONLY. I've always been a solid striker with my shorter irons, but have struggled with consistency hitting my longer irons. Purchasing F7 4-5-6 one length irons has fixed that problem. I couldn't be happier with these irons. My ball striking has improved greatly and my confidence level is now the same with these as it is when swinging my short irons. Just set up and swing like you are hitting your 7 iron. Keep at it and it will all fall into place. I highly recommend these irons!”

Nice Upgrade

Review by Charles W., 4 years ago.

“I received my USED cobra irons a couple of days earlier than the original date. I looked at them but honestly couldn't find a mark on any of them. The clubs I purchased were MINT and they really were in perfect condition.”
