O-Port
By replacing traditional pin-sized string holes with revolutionary giant O-Ports, a super aerodynamic frame has been created with a more responsive stringbed. This increases the sweet spot by 54%, creating a Sweet Zone, which means you hit your best shots … more often. What’s truly impressive is that the Prince engineers are able to do this all without enlarging the racquet head, increasing its length, or adding weight!
