MIRA C21 Gas Mask

"The C21 is Mira's premium CBRN mask, if you're a professional who needs features like removable outserts, comms compatibility, and a 6-point harness - or if you simply want the best - the C21 is for you." - Jonah Tyree, OHC Co-Founder

The C21 full face respirator features a NATO-standard connector fully compatible with 40mm threaded particulate filters. While the visor is ballistic-resistant for advanced eye protection, the C21 comes with a clear, and tinted outserts.  The C21 provides a comfortable fit around corrective eyewear while still allowing for a good cheek weld, allowing you unhindered use of your optics.  The entire mask is treated to prevent stagnation of chemical agents, for chemical resistance and ease of decontamination.

Fully compatible with most helmets, the C21 full face respirator is prepared to handle any and all CBRN threats with toxic chemical protection that meets or exceeds EN 136 requirements for a full face mask respirator. 

The C21 is offered in three sizes, as well as a variant for both right and left handed shooters. Size Medium will fit the vast majority of people, but as a general rule, for people 130lb or less with thin faces we suggest small. For users over 250 lbs with wide faces, go with large. Right-handed shooters will want to choose the left side filter mount, and vice versa.
