FR-x3™ is a revolutionary new fire-retardant fabric exclusive to 5.11 Tactical. This unique material contains 51% S.P.™ cotton and 49% FR-x3 modacrylic fiber. It inherits cotton’s natural breathability, comfort and ease of care, yet its fire-retardant nature is inherent to the fabric and doesn’t wash or wear out. FR-x3 exceeds minimum standards in NFPA tests for after-flame and no-drip properties according to ASTM D6413.

The FLASH Shirt is an extraordinary new product for operators who require protection from flash fires. Made from 6.8-oz. FR-x3™ canvas, the shirt is triple-stitched and bartacked for lasting durability. It features 5.11’s hidden document pockets and a smooth front placket. Cuffs are secured with hook-and-loop closures and the left sleeve features pockets for chem-lights. Two shoulder pockets and instructions are included so you can customize the FLASH shirt to suit your needs. Imported.
