Fabric Content:
FIREWEAR® 55% FFR™ (Fibrous Flame Retardant Fiber)/45% Cotton
An inherently flame resistant fabric blended from cotton and a fiber designed to smother flames when exposed to fire. The FFR™ Fiber is designed to emit a noncombustible gas through microscopic pores in the fiber when the fiber is exposed to a flame. This gas smothers the flames much like a fire extinguisher. FIREWEAR® fabrics are blended with cotton and thus have many of the natural benefits of cotton; breathability, high-moisture regain, and lightweight comfort.
