A swimming snorkel is a specially designed tube that allows swimmers to breathe underwater without turning their heads to the side. It is different from the snorkeling tube used in diving or sea swimming. Swimming snorkels are created with a central or frontal design that sits on top of your head and extends just above the water surface. This design helps swimmers breathe naturally while keeping their faces down in the water. The main parts of a swimming snorkel include the mouthpiece, tube, and head strap. The mouthpiece fits comfortably in your mouth, the tube allows air to pass through, and the strap keeps it securely in place. Some snorkels also come with purge valves that make it easier to expel water that enters the tube.
