The BOSS ONE K3 PRO MASTER brings the power of the Boss One line to a version designed for those who want to push hard without sacrificing comfort. In its blue colorway, it is the Master racket dedicated to the attacking player seeking solidity in their shots and a feeling of constant control.

The 3K carbon fiber frame ensures a soft and progressive response, accompanying the ball and filtering vibrations even during the most violent impacts. The sandblasted surface increases grip on the ball, favoring the generation of spin and precision in shots off the wall.

The Black EVA Soft Power Performance rubber ensures a powerful yet manageable ball output, with comfort that reduces fatigue during longer matches. The weight of 356–365 g adds mass and stability to the shot, while the medium balance of 25.5–26.5 cm keeps the racket responsive: a combination designed for those who want full power with handling that is always under control.
