Theanks for you input.
Yes no doubt: this is my windscreen
I also tried the Windblocker but with the same result.
The side-windows end just before my head and jus where my head is is the wind blows from the sides.
I am not extremely tall - 1.88 meter.
The seat has been put seat on the lowest stand.
So I wondered is there would be any piece of see-through plastic one could detache whether at the windows or at the roll bar
