The Long Bite Mouthpiece is standard on all Dive Rite regulators. Divers find that the longer bite tabs provide comfort and help prevent jaw fatigue. Besides the standard BLACK silicone, the Long Bite Mouthpiece is also available in BLUE, GREEN, PINK, and YELLOW. Colored mouthpieces are more than just a fashion statement, many tech divers use them on stage bottles as an additional way of labeling gases.
