Breathe easy in the conditions that make other regulators nervous. The Xstream Deep second stage's upstream design is exceptionally resistant to free flow — exactly what you want in cold water, strong current, or deep profiles. Its ambidextrous layout can be routed for left- or right-hand use, and it arrives Nitrox-ready from the factory with a standard 9/16" fitting. Choose all-black or a high-visibility yellow cover, and pair it with an Xstream first stage for the full Poseidon experience. Ask us about building your setup.
