Cressi MC9-SC Compact Pro Regulators

The MC9-SC/Compact Pro is designed to be used in cold water, making it versatile to be used anywhere on any trip.
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 metal while preserving the design flexibility, chemical resistance and physical and mechanical properties of a conventional thermoplastic.
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 can pass all the tests for use in cold water with flying colours.
