Engineered for Military, Law Enforcement & Emergency Response Teams

The CM-7M® CBRN tactical gas mask is a proven, professional-grade respiratory protection platform developed with Czech Army specialists for organizations requiring reliable CBRN defense and advanced optics compatibility. It delivers robust protection against chemical, biological, radiological and nuclear agents, industrial toxic gases and riot-control agents while providing a stable cheek weld for long-gun and optics use, low breathing resistance, integrated hydration capability, modular component commonality with CM-series masks for simplified logistics, and rugged construction suited to operational and fleet deployments.

Accepts standard 40mm NATO filters and comes in three sizes for a reliable seal across personnel.
