Description
The CM-7M tactical gas mask is the ultimate chemical, biological, radiological, and nuclear (CBRN) defense system when used in conjunction with suitable filters, such as the NBC-77 SOF filer, or breathing apparatus. The military-grade technology used for this full-face respirator provides comprehensive protection against the full spectrum of CBRN agents and toxic industrial chemicals in the form of gases, vapors, and aerosols.
The CM-7M CBRN tactical gas mask was designed and developed in cooperation with Czech Army specialists and specifically developed for use with a wide array of optics for advanced tactical capability.
The CM-7M hazmat mask meets the EN 136 (Class III) and EN 148-1 standards and is available in three sizes, providing a perfect fit for practically any user. A NATO-standard filter canister can be mounted on either (or both) side of the military mask to make it easier to aim a gun whether right- or left-handed.
The material of the facepiece (bromobutyl rubber) on this NATO gas mask provides extraordinary protection against all known chemical warfare agents, along with biological, nuclear, radiological, and industrial chemical agents.
This tactical gas mask is designed to withstand long-term use in any weather conditions. The inner mask features comfortable hypoallergenic construction that reduces the content of carbon dioxide in the mask and regulates the flow of inhaled air to prevent fogging for more comfortable all-day use.
The inhalation chambers on this army gas mask are fitted with the Rd 40 x 1/7” thread in accordance with the EN 148-1 (NATO) standard. This ensures compatibility with the widest range of filters readily available on the market today.
These military-grade gas masks are manufactured under the permanent supervision of a representative of the Czech Ministry of Defense and are trusted by military and police users in a wide variety of countries.
The lenses of the CM-7M warfare mask are specifically crafted to ensure compatibility with all kinds of optical devices while providing a sufficient field of vision. The dual lens configuration provides superior depth perception when compared to a single panoramic faceplate, making it ideal for use with rifle iron sights or in combat.
The CM-7M nuclear gas mask is equipped with a drinking system that enables safe drinking in contaminated areas. The drinking system is also compatible with CamelBak hydration systems.

SIZING
To size yourself, it would require a device called a faciometer which is not very common.
Size 2 (medium) fits 95% of the population, so if you’re an average size person, we would suggest size 2. For smaller than average people who weigh 130lb or less, with thin faces, we would suggest size 1 (small). For users over 250 lbs and wide faces, go with large.
QUESTIONS & ANSWERS
Would this mask protect me from the Coronavirus?
Coupled with the appropriate filter, other personal protective equipment to cover your skin, and proper decontamination measures, yes it will protect from coronavirus.
Would it be possible to get sunlight lenses or outserts for the CM-7M?
At this time, we do not carry any outserts or lens covers for the CM-7M, and we do not know of any aftermarket alternatives..
How would you know if a gas mask fits your face?
You would have to perform a negative pressure test. To do this, you would put the mask on your face, take a deep breath out, cover the inhalation valve (make sure the opposite side has the 40mm cap in place), and take a deep breath. If the mask sucks tight to your face without leaking air, you know that this mask fits.
What are the major differences between the CM-6M and CM-7M?
The CM-7M is specially designed for use with optics and operating a rifle. Features include a dual recessed visor system for eye relief, along with a contour above the inhalation valve for a closer cheek weld. These features come at the expense of a wide field of view, and this is where the CM-6M shines. Think of the CM-7M and CM-6M as different tools for different jobs.
Can glasses be worn with this mask and still create a tight seal? Also would a beard have to be shaved off?
Glasses cannot be worn with this mask as it would break the seal at the temples. There may be a 3rd party spectacle kit available for the CM-7M, but we do not know of any at this time. I would suggest contacting a company that specializes in spectacle inserts to see if anything is available. Considering a beard would break the seal of any gas mask, yes, it would have to be shaven off.
