Full Face Snorkeling Mask for Adults and Kids

Revised Product Description:

The HJKB K3 Full Face Snorkel Mask utilizes a unidirectional (outer) circulation breathing system that mechanically separates exhalation and inhalation. Inspiration enters through the dual breathing tube, while the exhaled carbon dioxide and the residual oxygen not inhaled are discharged from the outside of the mask, preventing carbon dioxide from re-entering the body and avoiding life-threatening or other accidents.

Advantages: 1. Prevents carbon dioxide accumulation within the mask, improving the safety of snorkeling. 2. Eliminates chest tightness and suffocation: the HJKB K3 Full Face Snorkel Mask has two snorkels that facilitate faster oxygen absorption. 3. Solves the mask leakage problem. The separate inlet and outlet ensure that even if you exhale carbon dioxide underwater, the inlet does not become loose and cause leakage.

Proper Usage: The Full Face Snorkel Mask is designed for recreational surface snorkeling only and is not intended to replace professional snorkeling or diving equipment. When snorkeling, take regular breaks and always follow the buddy rule – never snorkel alone. Before going out, test the mask in a pool to ensure a proper seal and fit.

To wear the mask, lift your hair back to avoid gaps between the mask and your face, and press the bottom of the mask against your chin to check for any gaps. If the fit is not optimal, adjust the tightness of the expansion band. After use, store the mask in the included mesh bag to prevent scratches that could affect future use.

Usage Instructions: - Before use, wipe the inside of the mask with the included anti-fog wipes to improve its anti-fog performance. - This mask is for surface snorkeling only (less than 3 meters/10 feet) and should not be used for scuba diving, deep diving, or free diving. - Hair or whiskers can create micro-spaces that allow water to seep in.

180° Panoramic Experience: The HJKB K3 snorkel mask features a 180-degree field of view, providing users with a wider and more immersive visual experience while in the water.

Action Camera Mount: The detachable action camera mount allows you to capture high-definition footage of your underwater adventures.

Anti-Leak & Anti-Fog: The innovative design of the K3 full face snorkel mask, with its separate breathing chambers, ensures maximum fresh air circulation and reduces fogging. The perfect silicone fit and seal make the mask waterproof, and a leaky valve allows water to be removed even if it accidentally enters the mask.
