- Safe and leak-proof breathing system: The snorkel mask uses a single-tube two-channel design that delivers double air intake compared to ordinary masks, maximizing air supply. A three-layer waterproof sealing ring ensures more even breathing on the surface and full water and leakage resistance for a safe, comfortable diving experience. - 180-degree panoramic design: Full-face mask with high-resolution transparent flat lenses provides a 180-degree panoramic view and a clearer, wider field of vision. With our children's snorkel mask, observing underwater landscapes and marine life is easy, helping you discover more during your underwater adventures. - Double anti-fog design: An inhalation and exhalation system promotes effective air flow circulation, prevents air mixing and fogging, and reduces discomfort when diving. The mask is coated with an anti-fog solution that maintains a clear view while resisting scratches and underwater pressure. - High-quality material and comfort: Made from high-quality plastic and medical silicone, the ergonomic design conforms to facial contours for a soft, comfortable fit. The widened elastic strap is adjustable to ensure a secure seal and effectively prevent water entry. - Foldable and portable: The adult mask features a snorkel folding design for quick folding with minimal effort, making it convenient to carry on trips or travel and occupying minimal space.
