A windbreak came with my car - I will check the history/documents to confirm but i think it was supplied by Mulfab.
I have only used it once to try - its ok-ish but will know more later in the summer when I will try it out a few times.!
It fits into brackets on either side in the rear luggage area. Is close behind the headrests and has a flap that clips to the hoop/tonneau poppers on rear to seal off the luggage area.
If I get a chance I will take a photo.
From what I remember it seemed ok up to 50mph or so with sidescreens on.
