Firefighters′ Fire Protection Head Cover White Rmt-Ma Flame-Retardant Head Cover

It is made of essential flame-retardant materials such as aramid fiber, and raw materials are dyed with raw pulp, which will not decolor after washing. It has excellent fire resistance and flame retardancy, and will not continue to ignit in case of open fire. Its large elasticity and good softness make the product easy to wear, comfortable and functional.
