I have been using Cabela's raingear for about 25 years.

They have excellent GoreTex jackets, pants and such - designed for those folks who have fun fishing in all day soakers. I spent all day in one soaker directing the efforts of a back hoe (he was dry) in my old Cabela jacket - and I was dry. You need a model with a storm flap over the zipper that velcros closed.

Another place to look - mountaineering gear. They don't put up with rain/snow/sleet reaching the zipper. They do charge, oh do they charge.
