Search and rescue (SAR) helicopter helmet

H-CMR SAR version is an entirely WATERPROOF (IP 67) helicopter helmet

The entire helmet has an IP67 rating, including the microphone and the speakers.
The H-CMR SAR version combine the advantages of the normal H-CMR (weight, sound attenuation, comfort...) with a specialized development, to meet the expectations of SAR missions or hostile environments.

Following dust and water immersion testing, all H-CMR helicopter helmet functionalities were maintained.
