The evolution of full-face masks for snorkeling. Natural breathing through your mouth and nose, with the lowest breathing effort in its category. Completely separate circuits for fresh air (IN) and exhaled air (OUT). Exhaled air is expelled through a SEAC patented exhaust circuit. Anti-fogging system guaranteed by the continuous flow of incoming air. One-way valves with a larger cross section for effortless exhalation and effective expulsion of residual CO2. The smaller internal volume offers an even broader field of vision and an optimization of residual CO2. A large anatomical hypoallergenic liquid silicone skirt with a shape designed to adapt to every kind of facial contour ensures the very best seal, safety, and comfort. The snorkel features a Dry Top to prevent water from entering the tube. Effective water elimination system uses a purge valve at the bottom. Silicone strap with co-molded colored insert. Two ways to adjust the strap, both in front and in the lower section. Quick-release buckles to release the strap instantly. Available in sizes L/XL, S/M designed for narrower faces and XS/S for kids (+10).
