NorthFace HyVent stuff is great and about as breathable as you can get for rain gear.
Had my northface hyvent gear for 14 years now and it is finally getting to the point I need to re-waterproof it. Stuff is amazing though and will keep you bone dry in the worst rain. Even better is that you can zip in a fleece liner and it is good down to below freezing.
For all day rain, I had good success staying dry in Cabela's Suede 4 Most Dry Plus Packable Rain wear. Not quite as breathable as their MT 50 goretex but keeps the rain out and not as expensive.
This stuff goes on sale for half off around thanksgiving every year, so about 200 bucks for top and bottom instead of around 500. It is also very good quality and for the money is hard to beat a cold weather/wet weather setup.
