This #9 head shape was originally developed specifically for Phil Mickelson for use on the PGA Tour. It was so successful that it was brought into the Odyssey line and has been a fixture ever since. The new White Ice Insert is our best feeling, multi-layer insert to date. Developed after extensive feedback from players on Tour, our engineers have enhanced the sound, responsiveness and consistency of the insert. Coupled with a new Dark Nickel finish to reduce glare, White Ice putters combine Tour-proven looks with Tour-inspired feel.
