I love Ventile - it is my" go to" fabric for all but the worst weathers! Invented for immersion suits during WW2 it IS waterproof when wet - for all practical purposes - but you need a good (wool) mid layer for comfort under it. I have used many different models of jacket/smock and currently use Smock, trousers and overtrousers in Ventile - all of which I designed and made myself.
I also like Cotton Gabardine fabric but find it even less hard wearing than Ventile as well as less wear resistant.
I dislike Goretex - overpriced, difficult to work with DIY, short lived, noisy and prone to failure (and smell) if not washed regularly ... and then retreated with a DWR spray.... and spark damages easily!
Ventile works when dirty, washes easily, repairs easily and can be sewn on domestic machines with no seam sealing needed.
There is no alternative!

- for me at least!
