In the late 1980's the East German NVA (Army) was upgrading a lot of combat gear and this is one of the pieces from that upgrade. While many thousands of sets were produced, most were never issued. My bag arrived in new, never used condition and I'll bet yours will be the same. These are for the old (heck, ancient by the time these were being produced) M1941 Russian mask. As such there's a LOT of room in this bag (the large filter lived in the bag and had a hose to the front of the mask-not inconvenient at all!) and it has dividers aplenty. AND it's waterproof! It does have nice big belt loops to attach to a belt, but you'll need to attach your own shoulder strap, as these don't have one. Still a great value for the money!
