One length clubs.

Review by Bowers Bounce - 7/13/2020

Did not even consider one length until I picked them up and held and gave each a part swing. I immediately felt really comfortable with them . Don't be put off by out of date thinking, give them a try.

Oh. My. God.

Review by AbsoluteHack - 7/1/2020

My custom one length irons came in yesterday. From hitting the ball all over the driving range within half an hour of getting used to clubs the ball flies straight as an arrow even on poor connection. 4 iron is now my favourite iron to hit in my bag!

Love these clubs!!

Review by J-Duffer - 6/4/2020

I’m a VERY high handicapper and For me these irons are an absolute game changer. Even my golfing buddy noticed an improvement in my game.
To start with every club carries 1-1/2 clubs longer than my previous set. It’s actually harder to get used to than one would think, but it’s a good problem to have!
I no longer have “favorite” or “most hated” irons in my bag. Every iron sets up and swings the same, and that’s the beauty of it!! I now grab a club based on distance as opposed to “can I hit this X-iron today”.
These are very forgiving... very. Im hitting everything straighter, even poorly struck shots. Very forgiving in case I didn’t mention that.
Couple the forgiving nature of the clubs, and the same set up with every club... everything seemed to improve at once across the whole set.
The only down side I’ve found with this set is, a big distance gap between the GW that comes with the set and my existing sand wedge. I added a 52 degree wedge to my bag that will hopefully be that club...
I’m not sure if these are the right clubs for everyone but I would highly recommend to anyone looking at replacing their irons to give these a serious look!!!

Review by GatorWil - 5/23/2020

Gained at least 1/2 club in distance and hitting significantly more greens. They are very forgiving and I can still work a draw or fade. I'm currently a 12 handicap and shot a 79 first time using them. Highly recommend!

Wow!!! Cobra One length ROCKS! Keep them a secret!

Review by Texasshark - 2/23/2020

I have played for 30 years and am a club junkie always wanting the best technology to improve and beat anyone around me. I started with Cobra and have tried every club in production since then.

The Cobra SZ One length irons are awesome!!!

Great quality with premium shafts, heads, and grips, these are game changers.

Very easy to get a great rhythm and hit GIR with each club. I chose 5-SW and this is so easy!

These are a must try!

These are the future, do not let your buddies know as you take their $$$.

Great Job Cobra!

Review by Miken - 1/29/2020

Very good club, am a huge fan of the one length concept. But, I’m not that fond of the wider sole on either the F9 or the new Speedzone.
I still prefer the F8 over either of the fore mentioned.

The New SZ Irons

Review by pkincy - 1/25/2020

Another great set of one length irons from Cobra Golf. Each year they keep getting better. The F7s were good, the F8s better, and the F9s were a huge improvement over the F8s. After two rounds with the new 2020 Speed Zones I think that Cobra has again fouind a way to continue to improve their lead in One Length clubs. The big change was from the F8 to the much wider sole on the F9s, but the SZs continue that wide sole, the toe and heel tungsten weights and have found a way to again make each successive set more foregiving and to keep the iron distance between clubs to the desired 10-12 yards per club.
