We are firefighters who invented the Hot Shield mask back in 1993 after the California Firestorms made us re-think our PPE. We saw the damage done to several local firefighters who were overrun, suffering severe burns to their faces. So right then we made it our mission to create a legit wildfire face mask that could stand up to the flames of a blowtorch. We've sold thousands of Hot Shields, of all different models & the Hot Shield is still the best protection you can get for wildland firefighting.
