Feature: 1. Upgraded Dry Breathing System: Different from the traditional breathing system, it adopts the M-type snorkel float design, which increases the intake and exhaust of the snorkel, increases the oxygen support rate by 67%, and makes the ventilation smoother. 2. Professional Design: Made of food-grade silicone structure, which fits the face softly without irritating abnormal objects on the face. The ergonomic design allows the snorkel mask to fit the face perfectly, completely wrapped without worrying about leaks. 3. Clearer Vision: This snorkeling mask uses high-quality PC flat lenses to make the vision clearer and more realistic, eliminating uncomfortable light distortion. With a 180 wide-angle field of view, you can explore the underwater world clearly. 4. Adjustable Headband: The headband has excellent elasticity, can easily fit different head shapes, is comfortable to wear and not easy to loosen, and does not pinch hair. When an emergency occurs, you can quickly break free from the mask to get out of the crisis. 5. Easy To Use: It is more friendly to beginners and swimming enthusiasts. Traditional diving equipment requires swimming by biting the breathing tube. Our full-face design allows you to breathe comfortably through your nose and mouth during snorkeling.
