Atmosphere is approved for cold water and features a unique highly effective de-fogging system which keeps the field of vision clear even at water temperatures close or equal to freezing point. The anti-distortion visor, with frosted sides prevents reflections and thanks to the over pressure technique the risk of contaminated water entering the mask is reduced. Any standard communication system will fit the Poseidon Atmosphere.

External buoyancy compensation weights are available add-ons which also could be used for mounting torches, video-cameras etc.
