DARKSPEED irons feature an all-new hollow construction that delivers Cobras longest iron design to date. 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.
