MSA Millennium Full Face Gas Mask CBRN Size Large Respirator 40mm Riot Controll. Most commonly used by organizations involved in riot control. I have a bunch of these and they are all in great condition. They have never actually been used. Just takes out of original packaging and stored. The masks may show signs yellowing that is typically seen on these preowned masks and they may have some very minor scratches from storage but the clear lenses are in near perfect condition. Slight white oxidation shows on Black rubber which is also very common but rubber is also in excellent condition with no cracking. They all come with a storage bag. I have small and medium available as well.
