The industry’s only fabric protecting against the three major hazards: Flash Fire, Electrical Arc Flash and Molten Metal, not only does Spentex® HP 6 oz. Fabric provide industry-leading protection, but it also yields unsurpassed breathability and comfort. Unlike FR-treated fabrics that lose their FR protection over time, Spentex® is inherently flame resistant, with FR protection built right into the fiber.
