I also ride in PNW. Rain or shine. My go to rain jacket and rain pants are from
J&G in Eugene, OR. Both are around 10 years old. Recommended. At that time each piece was $45. No idea what they are now. 30 years ago and a lot more disposable income and I spent the $$$ for Gore-tex but unless you are ice fishing you will be better off just cheaping out on coated nylon. You are going to get just as wet either way. In rain, especially in PNW, trying to stay bone dry is an exercise in futility. I try to stay warm. If I'm warm I can deal with some wet. J&G sell a helmet cover but I use a showercap. Pastel blue and pink in a two for $3.99 and I don't feel bad poking a hole in it for my helmet mirror. Rain chaps (Rainlegs) are worth what they cost.
