Cressi Sub Alpha Ultra Dry Snorkel allows divers to take every breath with confidence and focus on the reef below not on worrying about water in their air way. A generous bore slightly contoured tube provides ample airflow and a lower purge valve enables instant clearing if needed. The Alpha Ultra Dry Snorkel’s profiled 360° dry top automatically closes when submerged not allowing water entry regardless of the angle of the snorkel when you surface dive. Once you ascend back to the water’s surface, you can resume breathing from a Dry” snorkel tube. The corrugated flexible lower tube reduces jaw fatigue and allows the mouthpiece to drop away when not in use, making this one great snorkel for Scuba divers. The high-quality removable and replaceable silicone mouthpiece is comfortable and durable. The mouthpiece is also angled further reducing jaw fatigue. The Alpha Ultra Dry Snorkels streamlined design reduces drag while snorkeling and the dual release adjustable clip for securing the snorkel to your mask has its own streamlined shape to further reduces drag in the water. The Snorkel is available in multiple color choices, and is Italian made.
