Poseidon Atmosphere Full Face Mask
The Poseidon Atmosphere full face mask is equipped with one of the world’s highest performing regulators - the Poseidon Jetstream PP. It is approved for cold water and in combination with the mask, it features a unique highly effective de-fogging system which keeps the field of vision clear even at water temperatures close or equal to the freezing point. The mask has an anti-distortion visor, with frosted sides to prevent reflections. The mask has positive pressure breathing which is activated via a switch that can be easily reached even with thick gloves on. The positive pressure breathing system is a fail safe construction which if not activated will allow normal demand valve breathing. The mask can of course be used in all attitudes without free-flowing.

The regulator is approved according to the cold water standard EN 250:2000. The regulator has breathing performance that by far exceeds the demands of 3J/l at 50 m depth with a cylinder pressure of 50 bar. Many standard communication systems will fit the Poseidon mask. Developed initially for fighter plane pilots the mask was designed to be worn for up to six hours when the plane flies through chemical or biological war zones.
