Infinity Mouthpiece Soprano Sax

The Bari Infinity Polymer is the same CNC-machined design as the hard rubber version — same small chamber, same low step baffle, same focused dark tone with strong projection potential — built from a durable polymer material that handles conditions hard rubber doesn't always tolerate well.

Cold outdoor rehearsals, marching band, school instruments that get heavy daily use — the polymer holds up without cracking, warping, or reacting to temperature and humidity changes. It's a practical choice for players who need a reliable mouthpiece that can take some punishment, and a smart option for school programs looking for something that performs well and lasts.

The tone is focused and controlled with real projection available when you need it. For the price and the durability, it's hard to beat.

Two tip openings available. Size 6 (0.064" / 1.63mm) for more resistance and control. Size 7 (0.068" / 1.73mm) for a slightly more open feel. Cap and ligature included — we'd recommend upgrading the ligature when you're ready to get the most out of the mouthpiece.
