The Seac Sub Top Flex Snorkel model was conceived specifically for spearfishing and freediving. This snorkel was designed to ensure maximum comfort even after many hours of use. The snorkel mouthpiece material is liquid silicone. This simple yet effective J-style contoured tube design snorkel has no special valves or top to leak like on more complex designed snorkels. Snorkel comes with an easy to use snorkel keeper for attachment to the diver’s mask and is black in color. Italian made design.
