- Dual airflow design with a separate breathing chamber to prevent fogging. The dual airflow system provides a crystal clear view and offers a 345% improvement in breathing ease versus other full-face snorkel masks, making it one of the safest snorkel masks for adults. - High quality construction: soft, hypoallergenic silicone edges create a comfortable seal with the face and minimize air leaks. The silicone lining reduces water pressure on the face and insulates the mouth and nose from CO2, preventing discomfort and water entry. - 180° panorama: the adult diving mask features a shatter-proof safety window with a 180° wide underwater view. Clear flat HD lenses deliver an ultra-wide, ultra-sharp field of view without distortion, helping reduce dizziness for a clearer underwater experience. - Compatibility and use: supports natural breathing through the nose and mouth underwater without holding the snorkel in place. A camera mount (camera not included) allows you to attach a camera to easily capture snorkelling moments and share your experience with others. - Use scenarios: ideal for recreational snorkeling in open water or along reefs, pool training, and underwater exploration. The built-in camera mount enables hands-free filming of your underwater adventures.
