588 TT

  - Cleveland
The TT ("Tour Trajectory") variant of Cleveland's 588 irons features progressive blade length through the set, resulting in long irons with more forgiveness, but short irons that can deliver a more penetrating ball-flight. A shallow cavity and undercut also improves accuracy on off-center impacts. The faces are forged, while the multi-material head includes polymer and aluminum vibration dampening.

The 588 TT is designed to be interchangeable with 588 MT and 588 Altitude irons.
