Along with Paramo, Keela perhaps should also get a mention with their Munro Jacket. It all pretty good stuff along with Goretex (the best known) eVent and Triple Point Ceramic etc.

I wouldn't have a problem using any of these fabrics in the worst of conditions.

For high workout i.e. climbing the side of a mountain or cycling then there are some pretty good soft shell materials available as well such as Epic Soft shell. Although not completely waterproof, products like this EDZ Epic Sierra Cagoule might be worth a look.
