Cleveland Golf TT Irons Preview

Product Features

Cleveland is categorizing the various performance qualities of the 588 TT irons under three headings – Flight, Forgiveness, and Feel.


  • Engineered for Tour Trajectory – Constant blade height with progressive blade length promotes more forgiveness in long irons and controlled, penetrating trajectory in short irons.


  • Engineered Undercut – Modest cavity back with engineered undercut improves ball speed and accuracy on off-center hits.


  • Face Forged Technology – Every iron has a forged club face to enhance ball speed and feel.
  • Vibration Dampening – Multi-material insert of polymer and aluminum in iron plaque dampens vibration at impact for more consistent feel.
  • Fully Customizable – Part of the 588 Irons Family, Tour Trajectory Irons can be easily interchanged with 588 Mid Trajectory and Altitude Irons to customize a set with the perfect combination of ball flight, feel, and forgiveness.

  • Another solid looking set of irons! Like ddxu said, I love the fact that they did loft matching across this line for ease of creating combo sets.

    These appear to have a bit more forgiveness than I really anticipated. I need to hit these outdoors against the MT’s and see how they perform.

    Shafts will be an interesting part of this for sure as I have no experience with the stock ones.

  • Man, I like how I can mix and match since I have great confidence in 7-wedge but might need a little more in the MT line for assistance above that. They both look like great sets and can’t wait to hit these.

  • Cab you say forgiveness, these look like the Clevelands I’m used to seeing. I can see these in a combo with the 588 CB

  • I love the fact that Cleveland is giving people so many different options to make a bag tailored to their game. These look really nice and forgiving. Cleveland Staffers are a lucky group.

  • Another solid looking offering from Cleveland. Different options to suit a players skill level and wants is the right direction for any company.

  • I really like the understated look of the irons. Look like a hit!

  • Perhaps my favorite thing that was released today by Cleveland.

  • I seen a mean combo set between these and the MT

  • loft matching across 3 sets is a genius move by Cleveland, as well as building upon the technology and success of the 588 line. well done.

  • I like the way they tied them all together

  • Like what Cleveland has to offer this year.

  • Still looking at their new wedges and these irons look really good! A real good year coming up!

  • Simple chrome and black! No orange, purple or polka dots! LOVE EM!… and the ability to make a combo set is right on target. Thanks Cleveland!

  • These look really good to me, I look forward to hitting them but I am one who needs extra height on my irons, not a tour trajectory. My SS is gettiing slower as the years fly by.

  • Nice looking. I want to see if these feel and look different in person to the 588 CB’s. I like all the Cleveland offerings this year.

  • Just received mine from golfsmith they are a little thick top and bottom, I just handed down my mizuno mp60’s. I am looking forward to some forgiveness, distance and not losing accuracy. Cleveland has been making some great moves lately with equipment, wedges, drivers,putters now irons.
    I have not hit them yet, don’t think the adjustment will be to hard. Great looking irons looking forward to getting my -1.5 index to 0. Keep it up Cleveland !
