The Ultra 100L v4 provides a lighter alternative for players who want more arm-friendly playability without compromising the ability to hit with pace and depth. An all-new construction features FORTYFIVE° for increased stability and comfort through the swing, an all-new geometry expands the Sweet Spot Channel for additional power and reduces bulk in the beam for a smoother, more ergonomic design, and plant-based bumper, grommet and end cap components make this a winner off the court as a more sustainable solution. The v4 is highlighted by a neon pink colour that's sure to pop on court.
