The ST-100X boasts a robust construction starting with its heavy-duty silicate glass face shield. Unlike flat designs, this mask utilizes dual-convex face shield designs, offering an enhanced field of view and exceptional comfort. With a wider field of view, you can stay aware of your surroundings, which is crucial in dangerous situations. The burnt bronze lens prioritizes the safety of your eyes, shielding them against harmful UV rays, excessive light, and potential irritants.
Breathability is a key feature of the ST-100X, thanks to its dual intake valves. These valves support increased cardiovascular effort without inhibiting breathing. The intelligent ventilation structure ensures cooling airflow, keeping you collected and focused during intense moments.
Compatibility is another advantage of the ST-100X, as it works seamlessly with standard 40mm NATO threaded filters. This mask comes equipped with a durable P-D-1 40mm carbon-activated filter, independently tested to protect against non-oil-based particulates and organic vapors.
The ST-100X is the approved respirator for Wildland Firefighters by The Department of Homeland Security. If you need a reliable wildfire escape respirator, look no further. Click here if you would like to read more about this.
Comfort and convenience are prioritized with the 5-point harness. Designed for a universal fit, the harness stretches smoothly over the head without any snagging or pulling. It secures quickly and properly through the 5 pull tabs, ensuring a secure fit. The sturdy elasticized rubber straps retain their shape even in the hottest environments.
The face seal, made from soft yet durable natural rubber, provides a robust and airtight fit. The ST-100X is created for long-term use and can withstand harsh environments without wearing out, losing its shape, or retaining odor.
Combine the ST-100X with the Defense N-B-1 filter to protect against toxic industrial chemicals and materials encountered in non-terrorist and terrorist environments.
