Comfort and protection a compromise? NOT ANYMORE!
STEDFAST Inc. introduces a highly breathable, air permeable, flexible and flame resistant material offering superior particulate blocking performance. Stedair PREVENT, consists of a composite barrier made from Stedair moisture barriers proprietary technology.Firefighters neck and head areas are vulnerably exposed and highly sensitive to concentrations of toxic chemicals and permeation to the skin. Average hoods' offer a limited protection against these toxic particles. Stedair PREVENT offers oustanding breathability, increased air permeability and a unique construction for ease of movement and flexibility. These combined properties also enable Stedair PREVENT to minimize heat stress.
Stedair PREVENT when tested accordingly to NFPA 1971 not only meets the required 90% blocking efficiency but surpasses with results of 99.99% blocking efficiency with maginal loss after extreme conditioning against particle size.
