Blackhawk face mask made of NOMEX material. NOMEX material is superior in heat resistance and flame resistance, and has higher moisture wicking properties than cotton or cotton-blend fabrics treated with flame-retardant chemicals. It also maintains high breathability for a long time because the fabric is less likely to be damaged. It doesn't get bulky when worn under a helmet, and can be rolled up small and stored in a pocket.
