Hi,
For a day like yesterday, i wore a Snugpak Sleeka, which is actually the old miltary 'softie'. Its technically not waterproof, but even when soaking wet it is still warm. The best jacket I have ever owned and was ~£70. Its also short so can go over chest waders and you'd still wade fine. And made in uk.
For more outdoor pursuits, I like Buffalo Systems gear, another Made in UK company and great kit, more like a smock than a jacket but ideal for under waders on cold dreich days.
If you do want a proper waterprrof that can still breath and wick your sweat on a mild but wet day.....then the only thing to have is a Paramo. I have tried literally everything for days on the hills and for days out shooting, nothing comes close. But these can be a pricey piece of kit.
Hope this helps, I've spent many a day on the hills walking, shooting and in boats on lochs, tried many things.
