NEWEST VERSION SAFETY BREATHING SYSTEN: We focus on the safety of snorkeling. Unlike other single-channel or dual-channel snorkeling masks, full face snorkeling mask has three completely separate air channels, which can effectively prevent the re-inhalation of exhaled CO2, thus ensuring that you inhale fresh air every time. When you snorkel, you won't feel dizzy or even suffocated by inhaling a mixture of air and CO2, hence maximizing safety.
dual exhaust channels will double the ventilation rate, preventing exhaled gases entering the viewing visor and causing fogging. We choose food-grade silicone, which is safe, non-toxic, and has good elasticity. We adjust the edge of the silicone skirt according to Westerners' facial characteristics, effectively preventing leakage. We adopt a deeper silicone lining that won't put too much pressure on your nose bridge, ensuring your wearing comfort.
