Designed for professionals who need unseen safety in high-risk environments, our Inherent FR Underwear Top provides lightweight, breathable flame-resistant protection that layers invisibly under uniforms or outerwear. Available in Navy and Black, this base layer meets EN11612 (flame/heat), EN1149 (antistatic), EN61482 (arc flash), ASTM D6413, and ASTM F1959 standards—ideal for electricians, and industrial workers prioritizing comfort without compromising safety.


Key Features & Benefits:


Inherent FR Fabric: Flame resistance is permanently woven into the fibers (no chemical treatments), ensuring lifelong protection that won’t degrade with washing.


Multi-Hazard Compliance: Certified for arc flash (EN61482), electrostatic discharge (EN1149), and flame/heat resistance (EN11612)—critical for utilities, and chemical industries.


Layering-Ready Design:

  • Slim, Non-Bulky Fit: Seamlessly layers under shirts, coveralls, or jackets without restricting movement.

  • Moisture-Wicking Fabric: Keeps skin dry and comfortable during long shifts in extreme heat or cold.

Aramid Sewing Thread: Heat-resistant stitching prevents seam failure during flash fires or electrical arcs.


Durable & Subtle: Tagless design and colorfast fabric (Navy/Black) resist chafing and maintain a professional look under uniforms.
