This mask is designed exclusively for surface snorkeling at depths less than 10 feet (3 meters). Do not use for scuba diving, free diving, or deep diving, as pressure changes can be dangerous with full-face designs.

Yes, the innovative fish gill ventilation system actively circulates fresh air while expelling exhaled moisture rapidly. Combined with dual breathing tubes maximizing airflow, the anti-fog technology keeps your view crystal-clear throughout your snorkeling session.

Rinse thoroughly with fresh water immediately after each use to remove salt, sand, and debris. Allow to air dry completely before storing in the included mesh bag. Avoid direct sunlight exposure and harsh chemicals that could damage materials.

The mask is not designed to accommodate glasses underneath. The frames would prevent proper sealing and cause leaks. Consider prescription snorkel masks or contact lenses as alternatives for clear underwater vision if you need vision correction.

Adjust the elastic headband to find your optimal comfort level—it should feel snug but not painful. If discomfort persists, verify you've selected the correct size by remeasuring your face. The mask shouldn't require excessive tightening for proper sealing.
