1. 180degree HD panoramic view: The VolichtsSnorkel Mask for Kinr features transparent, flexible lenses, offering a crystalclear underwater view without distortion or blurring. Unlock a whole world of underwater adventures. 2. Dry breathing system: dry design with a twoway drain valve for effortless entry. The breathing mechanism outperforms traditional masks. When the snorkel tube is submerged, the float rises to prevent water ingress. When the snorkel tube is above water, the float lowers to allow fresh air into the lungs, ensuring comfortable underwater breathing. 3. Antifog antileakOur diving mask features independent inhalation and dual exhalation channels to prevent fogging and leakage, maintaining a clear view. The advanced leakproof silicone sealing technology (float system) effectively blocks water from entering the mask. 4. Safety comfort: Made of soft, nontoxic, and flexible silicone, our snorkel mask is gentle on the skin and resists collapsing when twisted. The drain valve hose includes a protective film to prevent scratches.
