as to how much frost protection can be achieved with fleece and under
what conditions? I assume it depends to some degree on wind strength.

In windy conditions at lower altitudes there is seldom frost, though we
might be in for a drop shortly if the weather forecast is correct.

But, when the two occur together, it is very damaging.
