Condition: Brand New Old Stock (NOS) / SealedCondition Guarantee: As collectors know, the vast majority of surplus XM28 masks have chemically degraded or "melted" over the decades. These to my knowledge and testing have avoided that fate, they are all flexible and the canvas packaging is still good and not brittle. The canvas is slightly yellowed though. The one open in the picture with the rest isn't for sell, nor is the other independent one, as they are either mine or a friend's. Point being they are in near perfect condition the straps aren't dry at all, nor is the plastic melty in any way.You can either buy one (1) sealed mask setup per purchase, or multiple.In the pictures I numbered them using my fingers to count going left to right. In case anyone wants to be that specific. If you want further infoPerfect for a Vietnam War collection or display.
