The mask was designed and developed in cooperation with Czech Army specialists and was specifically developed for use with a wide array of optics for advanced tactical capability.

The CM-7M fully meets the EN 136 (Class III) and EN 148-1 standards, and is available in 3 sizes. A canister can be mounted on either side of the facepiece to make it easier to aim a gun for either right-handed and left-handed people.

The material of the facepiece (bromobutyl rubber) provides extraordinary protection against all known chemical warfare agents, along with biological, nuclear, radiological, and industrial chemical agents.

The mask can withstand long-term use in any weather conditions. The inner mask reduces the content of carbon dioxide in the mask and regulates the airflow of inhaled air to protect the lenses from misting.

The inhalation chambers for filter connection are fitted with the thread Rd 40x1/7” in accordance with the EN 148-1 standard (NATO standard).

The masks are manufactured under the permanent supervision of a representative of the Czech Ministry of Defense.  

The lenses of the CM-7M mask were specifically crafted to ensure compatibility with all kinds of optical devices while providing a sufficient field of vision.

The CM-7M mask is equipped with a drinking device that enables safe drinking from a special plastic bottle in contaminated areas.  The drinking system is also compatible with CamelBak hydration systems.

Mask service life

The storage and service life of the CM-7M protective mask is 20 years from the date of production, provided that the recommended storage conditions are observed.

Durable and very well built mask

I'm insanely impressed with the quality of this mask, especially for the price point. I'm very glad I chose it over another very expensive mask I was comparing it to. Also Mira's customer service is out of this world. They will do everything they can to give you the best experience with them as possible.
