These parkas come from the 'Bundespolizei', the German Federal Police. This lineage is reflected in their design; unlike state police clothing, BGS gear is produced by the same manufacturers that supply the Bundeswehr. In fact the only difference between this, and some military parkas is a more olive shade of olive drab.
Some Germans aren't too happy about this. According to the German constitution policing is the responsibility of individual German states, not the federal government.
Regardless, everyone should have at least one olive drab military parka in their life, and it should be the real thing—not a department store knockoff. The Germans know what they're doing, they won't let you down.
