German police coveralls

I recently saw an olive drab coverall with a german police patch on the left shoulder for sale, but i haven't been able to find anything about it on the internet.

Here's what i remember about it :
-A sewn-on patch featuring three lions and "POLIZEI" on the left shoulder.
-Cargo pockets on both legs, they have metal zipper closure and i'm 90% they're placed on the front of the thigh.
-Two breast pockets, pretty sure they have zipper closure as well.
-The tag said it's a 65% cotton 35% poly blend (i think so), i also recall the number 58 (referring to size) written on the tag, a blue globe symbol, and a lot of text in german.

I would REALLY like any help on figuring out if this is real or not because you don't see German police jumpsuits every day.

Pockets to the front of the thighs to me indicates that the coverall is designed for the wearer to be sat down in their line of duty, perhaps a helicopter or vehicle crewman?

That's what i'm thinking as well, but the internet has no idea whatsoever what this thing is.

I also forgot to mention it has belt loops on the torso.

I also found out something about the patch, it's used by policemen in the Baden-Württemberg region.
