A flex snorkel is a type of snorkel that features a flexible section at the bottom of the tube, usually it is made of corrugated silicone. The flexible section allows the snorkel to bend and move with the natural movement of the diver’s head and neck, reducing stress on the jaw and increasing comfort during extended use.
Flex snorkels typically have a semi-dry or dry top valve at the top of the tube, which helps prevent water from entering the snorkel while the diver is swimming or diving. Some flex snorkels also have a purge valve at the bottom of the tube, which allows the diver to easily clear any water that may have entered the snorkel.
Flex snorkels are popular among snorkelers and scuba divers, because they offer a comfortable, ergonomic design that reduces jaw fatigue. Some flex snorkels are straight and some have a slight curve. Why is that? The straight flex snorkel is the preferred option for scuba divers. When they are under water, where they don’t need the snorkel, it simply falls away and does not interfere with the regulator or other breathing equipment.
Snorkelers may prefer the curved version of the flex snorkel, as it bends with the natural movement and thus reduces jaw fatigue.
