- Leak-proof anti-fog design: made of liquid silicone, the mask flexibly fits different face shapes while maintaining leak-proof comfort. The breathing channel is fully isolated from the lens to prevent fogging. It can also be used as swimming goggles or diving goggles. - 180-degree panorama: features a professional high-resolution anti-fog flat lens for a wide field of view, high light transmission, and reduced dizziness. Provides clear, wider underwater vision. A camera mount allows you to record moments underwater. - Safe Airflow System: includes a fully dry snorkel system that shortens the snorkel tube while expanding the diameter for faster draining and easier breathing. The movable float design prevents water from entering the top and the snorkel, reducing choking risk. Suitable for snorkeling, free diving, and swimming. - Comfortable and lightweight: lighter than traditional full-face masks and designed for summer use without stuffiness; weight is about a quarter of the old full-face mask. Adjustable straps enable a comfortable, secure fit. - Use scenarios: snorkeling in reefs or pools with a wide underwater view; free diving or casual swimming with easy breathing; underwater moments can be captured with the built-in camera mount for photos or video.
