Hollow-headed 3- through 6-irons have
a thin, "unsupported" face (it creates a "wraparound"
design) that leads to increased clubface
flexibility. This combines with the firm's "inverted cone"
design to boost ball speed across the face. The hollow
chamber is filled with lightweight foam and a silicone
shock absorber to control pitch and sound. R9 short
irons have a low-CG sole design and vibration dampening
layer in the cavity.
