The Apeks Comfo-bite Antimicrobial Mouthpiece by Aqualung has a unique "bridge" that fits across your upper palate so bite pressure is not required to hold the mouthpiece in place. This feature will noticeably reduce jaw fatigue some divers experience when holding a regulator in their mouths for extended periods. This mouthpiece is popular with technical divers and fits all brands of regulators we sell plus most other brands, except Poseidon. This is the genuine OEM product and not a generic copy. Available in a hypoallergenic firm flexible silicone, we also include a tie wrap to attach the mouthpiece to your second stage. The black color mouthpiece is produced in two sizes, standard (for adults) and small (for children), although the { 1.2 x 0.65 in | 3.0 X 1.6 cm } opening for the regulator orifice is the same for both sizes. The standard mouthpiece is also available individually in a choice of green or yellow color.

The Apeks branded version of the Comfo-bite mouthpiece material is also compounded with a tasteless and odorless silver-ion technology featuring antimicrobial properties. The material is FDA (Food and Drug Administration) food-grade safe and EPA (Environmental Protection Agency) approved to provide active protection against viruses, mold, yeast, algae and bacteria.
