The MK2 EVO comes with the patent-pending Extended Thermal Insulating System (XTIS) that lets you enjoy an ultra-fast breathing response and maximum airflow with minimal effort -- regardless of how cold the water is. The XTIS makes this possible by fully isolating the mechanical elements of the first stage from the cold, increasing freezing resistance by an average of 50 percent over the previous MK2 first stage.

The MK2 EVO is the only downstream piston-style first stage with internal components specifically designed to resist freezing in extreme cold-water conditions. It is also ultra compact, yet it has a bigger piston that pumps out 15 percent more airflow from a smaller package. So you can expect top-notch breathing performance whether you're reef diving in the warm Caribbean or wreck diving in the chilly Great Lakes.
