Lot's of great gear available. My system keeps evolving. I do believe what works for me here in SW Idaho is different than what works best in others, particularly wetter ones. We simply don't get a ton of precipitation at one time.
That said, I have found the simple, but very light and packable "Space Rain" gear from Cabela's is always in my pack. I do have Cabela's Goretex MT050, which is great when I am going out into a KNOW raistorm or a ton of melting snow off trees. Typically many goretex jackets are too heavy.
I have finally spent some $$ on Sitka gear: Mountain Pants, Jetstream Jacket, and Jetstream Pants. Typically these are fine without a lot of rain. Can be too warm in direct sun above 60deg, otherwise just add layers as it gets colder. For heavy rain, I either replace with SpaceRain jacket and pant, or cover with it. Love the flex in the fabric, compared to what I used to use. Love the pockets as well. Seem to hold up well, after using for probably 45 days in the field from Sept to Jan for scouting, Goat hunt, and chukar hunting.
