Atomic Aquatics has a reputation for listening to divers' feedback and continuously enhancing their products. In response to divers' requests for a more durable and comfortable mouthpiece, they introduced the acclaimed Dual-silicone Comfort-fit Regulator Mouthpiece, initially paired with the M1 regulator. Crafted from a combination of two silicone materials, this mouthpiece excels in both durability and comfort, making it a top choice for any diver.
