A classic "J" style snorkel that has been tried and true, the simple design makes this snorkel almost bullet proof and reliable compared too many of the newer hi-tech snorkels on the market. No fancy valves on top or bottom, if you can blast clear a snorkel than this is what you want. The Seac Jet Freediving Snorkel has a durable, yet comfortable liquid silicone mouthpiece that allows prolonged freediving excursions. The contoured snorkel tube is made from a PVC material for long life and reliability. The ergonomic designed tube is comfortable and helps streamline the divers profile in the water. Snorkel includes an easy to use quick disconnect snorkel keeper and is available in multiple colors.
