- Comfortable and lightweight: compared to a full face mask you feel less stuffy in summer, and the mask weighs only about a quarter of the old full face design. The snorkel set includes adjustable straps to achieve the most comfortable fit. - 180 degree panorama: professional high resolution anti fog flat lens provides a wide field of view, high light transmission and no dizziness. Enjoy a clearer and wider underwater view and use the built in camera mount to capture moments underwater. - Leakproof and anti fog design: the mask body is made of liquid silicone to adapt to different face shapes with a high standard of seal and comfort. The breathing channel is fully isolated from the lens to prevent fogging. It can also be used as swimming goggles. - Safe airflow system: the fully dry snorkel system shortens the snorkel tube and increases the diameter for faster exhale and easier breathing. The movable float design prevents water from entering from the top, reducing choking risk so you can snorkel, dive or swim with confidence. - Use scenarios: ideal for reef snorkeling trips and open water exploration; suitable for underwater photography or videography with the camera mount; convenient for pool training and casual swimming with a compact, dry top mask.
