I must confess, I'm a bit fussy when it comes to winter clothing, I only wear Paramo, very expensive but you only buy it once, lasts forever, waterproof, breathable, light, rustle free, and definitely does what it says. For footwear it has to be Brasher hillmaster GTX Goretex.....fantastic, dry and warm, all the above are also used for hiking, so dual purpose.
Here is a idea of prices
Jacket Paramo Alta 11 £180
Trousers waterproof Paramo Cascada £110
Brasher boots £115
Worth every penny

I know to some this will seem a lot of money, but I have had them for 5 years and they are still like new, I do go hiking in horrendous weather, always warm and dry.
