Full Face Snorkel Mask with Dual Breathing Tubes

We use unidirectional (outer) circulation breathing separation, separate the exhalation and inhalation mechanically. Inspiration enters through the dual breathing tube. The carbon dioxide exhaled as well as residual oxygen not inhaled into the body that discharges from the outside of the mask respectively to prevent carbon dioxide from entering the body to cause life-threatening and other accidents.

Advantage：

1.Prevent carbon dioxide accumulation inside the mask to improve the safety of snorkeling.

2.Get rid of chest tightness and suffocation：DEMMET K3S Full Face Snorkel Mask has two snorkels， absorbs oxygen faster.

3.Solve the mask leakage problem. Because the inlet and outlet are separate，so even if you spit out carbon dioxide underwater, it does not let the inlet buoy loose to leak.
