Reserve Evolution Mouthpieces are milled (not molded) from hard rubber for a higher level of consistency; every Reserve mouthpiece is machined to the strictest tolerances. Of course, the true beauty of Reserve lies beyond its polished angles, curves, and proprietary material to something far more remarkable: its sound.

Features

• Altered baffle for added projection and articulation nuance
