In order to achieve extremely high performance in low temperature environments, the second stage in particular was designed with the special Thermoconductive Thermoplastic Neopolymer that has the capacity to transfer heat like a metal while preserving the design flexibility, chemical resistance, and physical and mechanical properties of a conventional thermoplastic. Therefore it makes it possible to drastically reduce the weight while delivering heat conductivity on a par with metal cases. Thanks to this material and a specially conceived purge valve, it passes EN 250 cold water tests.

The MC9-SC (Seal Chamber) 1ST stage is environmentally sealed, protecting it against icing in cold water and against contamination from particulate matter in silty conditions.

If you're going to dive all over the world, and want your regs to perform consistently between temperate and tropical waters, then you want something designed to deal with temperature ranges.  The Cressi MC9SC, paired with the Compact Pro does exactly that, plus it's small & lightweight, making it both travel & jaw-friendly!
