Cobra BiO CELL+ 4-PW, GW Iron Set with Steel Shafts

The Cobra BiO CELL+ Iron features tungsten-powered performance that delivers the ultimate in distance and control.

Multi-material construction with tungsten cell weighting: The long and mid irons feature heavy tungsten in the heel and toe to provide a higher moment of inertia (MOI) and faster ball speeds for greater distance and control. The short irons come with tungsten centered behind the hitting area for the ultimate in control and feel.

Perimeter undercut design: The large unsupported face creates a thinner face with more flex at impact for increased ball speeds and extreme distance.

E9 Face Technology: This enables more discretionary weight movement to provide a thicker section behind the typical impact area as you progress through the set. The result is a lighter, hotter face without sacrificing feel.
