The Ergo Dry is a high quality snorkel and also one that lives up to its name. The snorkel has a 100% dry top, which prevents water from entering the trachea. The waterless valve on the mouthpiece also ensures that water does not enter your mouth immediately and that the snorkel is easy to clear of water. This makes it ideal for diving or for long snorkeling sessions. The snorkel holder is movable and hinged.
