Multi Safety Support System


About us

M3S specializes in the development of breathing apparatus. The company, located in the Var County (France), was founded by Bertrand HEMARD and Alexandre FOX in 2012. The entire team at M3S is passionate about scuba diving and cave diving.

Our underwater experiences and passion for diving led us to embark on this insane challenge of reinventing the diving rebreather. M3S has managed to innovate, develop and manufacture the TRITON, a mechanical chesmounted rebreather intended for all recreational and technical divers.

The TRITON is the smallest and lightest rebreather on the market, as well as the easiest to breathe. 


The TRITON has extended beyond recreational and technical diving due to its acquired expertise, and is now being used in professional and military environments.  

We advocate the  « Made in France » which has led us to partner and collaborate with several French companies specializing in their respective fields.
