The Cressi America Dark Snorkel is designed specifically for the needs of free divers.
The Supernova Cressi Dry snorkel has a unique Splash Guard at the top which greatly reduces the entrance of water during use on the surface. The special Valve on top seals the tube as you dive, almost totally preventing the entrance of water when the snorkel is submerged.
Alpha Ultra Dry snorkel allows users to take every breath with confidence and focus on the reef below. Features a float mechanism which closes instantly to prevent water from entering the snorkel whether accidentally or purposely submerged.
