Absolutely! Sealenzi uses a proprietary Dual-Tube Airflow system that separates fresh air intake from exhaled CO2. This ensures you are always breathing fresh oxygen and prevents the buildup of dangerous gases often found in cheaper, single-tube masks.

Yes. By separating the breathing chamber from the viewing lens, the warm air you exhale is directed out through side channels instead of hitting the lens. This physical separation is much more effective than simple anti-fog coatings.

No, Sealenzi is designed specifically for surface snorkeling. Full-face masks are not suitable for deep diving (free-diving) because you cannot pinch your nose to equalize ear pressure as you go deeper. It is perfect for floating and exploring shallow reefs.

The Dry-Top system uses floating balls to seal the tubes if they go underwater. If a tiny bit of water does leak through the seal, there is a one-way purge valve at the chin. Simply lift your head out of the water, and the water will drain out automatically.

Measure from the bridge of your nose to the bottom of your chin. If it's less than 4.7 inches (12cm), choose S/M. If it's more than 4.7 inches, choose L/XL. The adjustable straps allow for a very customized and snug fit for both sizes.

Standard glasses will prevent the silicone from creating a tight seal against your face, which will cause leaks. We recommend using contact lenses or prescription snorkel mask inserts for the best experience.

Yes! The snorkel tubes are completely detachable, making the mask flat and easy to pack in your suitcase. It even comes with a mesh carrying bag to keep all the parts together and help them air dry after use.
