We now have Reiterhosen, copied from an original pair that was issued to the enlisted and NCO ranks.
Reiterhosen are not simply breeches with leather added to the seat and inside of the legs. If you've ever closely examined an original pair, you'll see that they are quite different in construction! They require as much time to make as an early tunic!
You have a choice of suede or smooth leather, and either steingrau or feldgrau melton wool.
