Sniper gear for wet weather

[sonofsammo]

What do you guys wear under your ghillies when it's going to piss it down all day?
I wear a Northern Mountain 3d leaf suit, which is grand - except it's full of holes.
I found out on Sunday my current kit just ain't up to the job  - I used a combat 95 smock, which was puddled very quickly. And a crappy highland waterproof which was less use than a bin bag, as I soaked within minutes from the inside out.
As a result, I'm looking to get hold of something better.
I definitely want to stay warm, and if I could stay dry too, that would be a bonus!

I'm not a great fan of gore-tex, as I have never got on with it whilst hillwalking etc... I soak from the inside out!
I tend to use a paramo jacket for that sort of thing.

Any suggestions that won't break the bank would be most welcome.
I'm currently looking at something like:
Paramo cascada ii trousers with 

either Paramo cascada jacket
Or a Buffalo special 6 shirt

But if there are any better ideas, that would be most helpful!
TIA ?

What about a ghillie poncho, made with an actual waterproof poncho?

Helikon does a nice multicam/m81 one, a bit of shoe goo to attach netting onto and then have fun with artificial stuff.

Camouflaged AND protected from rain.
