The M-65 German Bundeswehr gas mask is constructed of standard, high-strength, flexible O.D. rubber and features large triangular eye pieces for superior vision, a voicemeter for improved verbal communication, an upgraded exhalation valve for easier breathing. The M65 mask was originally designed to protect against nerve gas, blister agents, choking agents, tear and harassing gases, blood gases, incapacitates and toxins. Occasionally, masks will have some wear around eye pieces where the paint has rubbed off. Filters sold separately (40mm).
