Diving Mask: Our full face diving mask adopts high-definition flat lenses, which can provide a clear and distortionless 180 panoramic view, surpassing standard diving masks. Its full face design allows you to breathe comfortably through your nose and mouth during snorkeling. and anti fog: Our snorkeling mask is made of food grade silicone, which will not irritate the skin and is fitted to prevent leakage. This ensures that the mask remains dry at all times and prevents exhaled carbon dioxide from reaching the mask and causing fogging. Leak proof design: Our ventilation pipe mask adopts a leak proof design, using a ball to close the air valve underwater to prevent water from entering the mask. When on water, the ball descends and the air valve opens, allowing air to enter the breathing tube. This design ensures that water does not enter the mask from the top and can breathe comfortably during snorkeling. The best gift for beginners: Our full face snorkeling mask is easy to use and more suitable for beginners than traditional diving masks. It also comes with a detachable camera holder, allowing you to record underwater adventures and leave unforgettable memories with family and friends.
