The lightweight LAGUNA 2 features a proprietary dry valve on the top of the barrel that immediately closes upon contact with water. This makes it incredibly easy to get a full breath of air immediately upon returning to the surface after a freedive descent. It also keeps water splashes out of the barrel when surface swimming. The ergonomic mouthpiece eliminates jaw fatigue, and a very efficient self-draining purge valve makes quick work of any water drops that manage to get inside the snorkel. The flexible, corrugated lower section is easy to use and drops away from the face when not needed.
