Micronel (Scott) m95 nbc 40mm respirator size medium open box new old stock. Upgraded with speech diaphragm on right side filter port for clear speech but can be switched to left or removed if dual filters are desired. As with all of these m95 masks the drinking port cover gets brittle and usually breaks in some way. This one has the tab to the drinking port cover glued back on for best display esthetics and the bottom hinged section of the cover is no longer attached do to the same brittle issue. Fantastic condition otherwise and does not effect its functionality. Contact me with any questions.
