The Poseidon Atmosphere fullface 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.
For best performance, the mask should be connected to an Xstream 1st stage.
