Ergodyne - EGO16820 Made with flame-resistant protection and thermal material, this 6820 FR Knit Beanie shields you from the cold and protects you from flash arc hazards. Flame-resistant feature extinguishes on its own to keep workers safe in high-intensity working conditions. Soft, warm, 40 percent cotton and fleece lining maximizes comfort. Wear beanie under headgear for added warmth without bulking. Reflective accents protect workers in low-light conditions for optimum safety. This hat is ideal for workers needing protection and warmth such as electrical, manufacturing and construction workers. Wear beanie while hunting, skiing or climbing as well. Designed to withstand wear and tear, machine-washing will not reduce fire-resistant material. Beanie has been tested and proved to ASTM F1506 and NFPA 70E standards for safety and protection involving arc flash risks.
