Keeps Water OutThe Impulse has two valves: if a wave breaks over the snorkel, the upper valve directs most of the water out before it reaches the mouthpiece. But if water does get past the first valve, it will drain out through the lower valve.
Clears EasilyIn the unlikely event that you would need to clear the reservoir below the mouthpiece, all it takes is a gentle puff of breath.
Eliminates Jaw FatigueOur patented Comfo-Bite mouthpiece does not necessitate clenching your teeth, reducing fatigue, even after hours of adventure. Mouthpieces are replaceable. (Available in two mouth sizes.)
