Our patented side inhalation and exhalation connector system allows easy switching between left and right configurations. This innovative design ensures optimal performance for all users, regardless of shooting preference or tactical setup.
The C21 features a NATO-standard connector fully compatible with 40mm threaded particulate filters. The breathing apparatus can be adjusted to accommodate left and right shooters, while the air connector system features advanced technology that prevents contaminated air from leaking into the mask during filter replacement.
The visor is ballistic-resistant for advanced eye protection and provides a comfortable fit around corrective eyewear or visual aiming systems. 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 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.

Determining your ideal respirator fit depends primarily on facial dimensions. While specialized measurement tools exist, we've simplified the selection process:
The mid-size option accommodates approximately 95% of users. Consider choosing small if you have a petite build (under 130 pounds) with narrow facial features. Those with broader faces or larger builds (exceeding 250 pounds) typically benefit from the large size.
Verify proper fit through the seal check: Block the intake valve and inhale deeply - the mask should create a tight seal against your face without air leakage.
Remember to separately purchase compatible filters and select your preferred size from the available options.
