【HJKB INDEPENDENT PATENT RESPIRATORY SYSTEM】HJKB 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. HJKB 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】HJKB 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.
