Product Information

The snorkeling experience reaches a new level thanks to the Seac Libera, the top of the range among SeacSub S.p.A .. panoramic full-face snorkelling masks. The Seac Libera combines all the best qualities of the full face masks from Seac. The wide panoramic screen in polycarbonate allows a perfect view of the bottom. The Seac patented breathing system directs the inhaled and exhaled air into two completely different channels. This allows natural breathing without any effort, and prevents fogging of the glass due to air exchange. The snorkel of the full face Seac Libera mask is equipped with a dry top system that prevents the entry of water from above in case of accidental immersion of the tube and has bright colors to be clearly visible on the water surface. The Seac Libera is available in 3 sizes, depending on the distance from the nose to the chin: XS-S (<10 cm), S-M (10-11.5 cm) and L-XL (> 11.5 cm). The XS-S size, for greater comfort, presents, for the first time, not only a reduced skirt but also a smaller body, which lighter and more pleasant on smaller faces. In all three sizes the skirt is made of high quality soft hypoallergenic silicone. The Seac Libera's straps are also made of silicone and can be adjusted both at the top and at the bottom of the head for a perfect fit. Another great innovation is the quick-release buckle on both sides of Seac Libera which allows you to quickly remove the mask with just one hand. The colors and lines of the Seac Libera make it a particularly exciting as a full face mask, perfect for those seeking maximum comfort and safety while snorkeling without sacrificing style. The Seac Libera full face mask is recommended for adults and children aged 10 and up.

Frequently Asked Questions

How do I choose the right Seac Libera size?

Measure your nose-to-chin distance: under 10 cm takes XS-S, 10 to 11.5 cm takes S-M, over 11.5 cm takes L-XL. Under 10 cm takes the XS-S, 10 to 11.5 cm takes the S-M, and more than 11.5 cm takes the L-XL. The XS-S also uses a reduced body shell, which lightens the mask and improves the fit on smaller faces.

Does the Seac Libera fog up?

The Libera is built to resist fogging. Its patented separate channel breathing system keeps inhaled and exhaled air in completely different channels, so warm, humid exhaled breath is not directed across the lens. The result is a clear wide panoramic polycarbonate screen plus easier, more natural breathing through the nose and mouth.

Is the Seac Libera suitable for children?

Seac recommends the Libera for adults and children aged 10 and up. For younger or smaller faces, the XS-S size fits a nose-to-chin measurement under 10 cm and uses a reduced body shell that lightens the mask and improves fit on smaller faces. Always check the measurement rather than guessing by age alone.

What happens if water gets into the mask?

The Libera uses two features to deal with water. The dry top snorkel system closes off the tube to prevent water entry if the snorkel is accidentally submerged, and integrated purge valves let any water that does get inside drain out of the mask. Quick release buckles on both sides also allow fast single-handed removal.
