hi mate, i dont know what your price range is, but i have used a Hien Gericke "VOYAGER II" suit for 2years now and it is excellent.
removeable thermal liners in jacket and pants.
removeable bib n brace chest warmer.
removeable neck/face warmer.
zip together 2 piece suit.
armour in places,including back protector.
completely waterproof and breathable for over 2 years now,never been washed or treated.
it cost me £350 back then, which i thought was a lot, but every time i wear it i congratulate myself for a rare spark of good sense! with all the bits zipped up its like putting a waterproof quilt on, and also a nice loose thin jacket for the summer(but still armoured)
money well spent, and probably loads cheaper elsewhere in europe.
