【 INDEPENDENT PATENT RESPIRATORY SYSTEM】We invited dozens of designers from the UK and Australia to create this unique snorkeling breathing system. We use unidirectional circulation breathing separation to separate the exhaled and inhaled mechanics so that exhaled CO₂ and residual O₂ are expelled quickly from the outlet. We provides a safer snorkeling experience for you!

【180° PANORAMIC VIEW & ANTI-FOG WIPES】Optimized lens shape and delicate lens for the wider field of view and 30% better distortion-free visibility. To remove CO₂ in time, when it exhales from the outlet, some bubbles will be created which may temporarily affect your vision but will make you safer and breathe more smoothly. Each set of snorkeling set is equipped with an anti-fog wipe, wipe the internal mirror before snorkeling can reduce the fogging to some extent.

【INHALE IN MORE SMOOTHLY】Our Snorkel Mask adopts two breathing tubes, compared with the old snorkel mask, our double vent full face snorkel mask makes breathing more smooth. Feeding fresh air circulation by the mouth and nose together， makes you more relaxed while snorkeling. The new breathing mode avoids blockage of a single breathing tube and doesn't worry about leaks or choking water.

【MEDICAL ORIGINAL MATERIAL AND SIZE】Our Full Face Snorkel Mask Made of High-Quality PC and Medical Grade Silicone. Non-toxic and environmental, which can prevent skin allergies or other skin problems caused by original materials. The size is measured from the nose to the bottom of your chin. If less than 4.7 in(12cm) and please select size S/M, if more than 4.7 in(12cm), and please select size L/XL. Generally, S/M is for women, and teenagers（Also applies to older kids）, L/XL is for men.

K3 Full Face Snorkel Mask

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：HJKB K3 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.
