Product details:

Cobra's AIR-X irons are a lightweight design with effortless speed and great feel to improve swing tempo. The lighter iron head and components make the club significantly lighter and easier to swing than traditional irons. The variable thickness face design is thinned in the heel and toe to create more speed on off-center strikes. A low profile, cavity back design features stronger lofts to help players launch higher and farther. An offset hosel reduces that nasty slice for straighter, more accurate shots.Lightweight Design-Air X Irons feature a lightweight design to promote great feel, and effortless speed for the smoothest swing tempos
