Pinch-free nosebridge comfortably contours to the bridge of the nose, eliminating the discomfort and constant readjustment that is necessary with metal nosebands. Exhale valve lets hot air out easier, reducing breathing resistance, which keeps workers cooler and allows masks to last longer. Exclusive Dura-Mesh® shell resists collapsing in regular use and even under hot and humid conditions. Added carbon layer helps filter out nuisance levels of ozone and organic vapors (less than OSHA PEL). Meets heat and flame resistance in accordance with ANSI/ISEA 110-2003 Section 7.11.1.
