The Cressi Pro MC9-SC Regulator achieves a high performance in both cold and warm waters. In order to achieve extremely high performance in low temperature environments, the second stage in 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. That is, 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 passed on 250 cold water tests
