Fires are unpredictable — situations can change in an instant with temperatures reaching 1900 degrees F, leaving workers vulnerable to serious injury. Nomex® III A is a blend of 93% Nomex® with 5% Kevlar® and 2% antistatic fiber. This innovative fabric helps minimize break-open, and expands to form a stable and inert barrier between the fire and skin. This gives wearers the valuable seconds they need to escape from the hazard. Our vest is special designed for tactical needs with ability to carry various tools.
