By replacing the traditional pin-sized string holes with 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 Prince did it all without enlarging the racquet head, increasing it's length, or adding weight. So it's easy to maneuver and quicker through the air.

The new O³ engineered racquets are created through a one step fusion process that utilizes the strongest structure known to mman, the Arch, creating the frame's O-Ports. These O-Ports stabilize the racquet and provide total string freedom for a livelier response across the entire string bed. This eliminates the dead zone that traditional string holes create, giving players more consistency, greater stability and more confidence to hit their best shots more often. In addition, the O-Ports aerodynamic design provides a faster swing speed, enabling players to reach more balls and win more points, more often.
