DARKSPEED irons feature an all-new hollow construction that delivers Cobras longest iron design to date. One Length irons offer repeatable setup and swing consistency to boost confidence from every distance. The hollow cavity in the head is filled with a softer foam material to mute vibrations and improve sound. A larger PWRSHELL L-cup face maximizes launch and distance, with an A.I. designed H.O.T. face creates more efficient speed and spin, with a larger sweet spot. A refined PWR-BRIDGE weighting system offers an more unsupported face and extreme flexibility.
