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 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.

CM-7M Military Gas Mask Service Life. The storage and service life of the CM-7M full-face respirator / tactical gas mask is 20 years from the date of production, provided that the recommended storage conditions are observed. 5.19 – 5.51 inch (small). 5.51 – 5.82 inch (medium) (universal most used). 5.82 – 6.14 inch (large). 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. You will know the size is right if you do a negative pressure test (blocking the inhalation valve and taking a deep breath), and the mask seals tightly to your face. Filters are NOT included. Comes with FREE CBRN Hood for added.
