I've used the HH Impertech for years and it's fantastic rain gear BUT, you don't want to have to hike longs slogs in that stuff, it doesn't breath at all and you will sweat like a hog in it. That said, I have a set of the bibs and a guide jacket and use them whenever it rains. If your planning on doing a lot of moving I would suggest the something that utilizes either Gore-Tex of eVent. Westcomb is damn good stuff but it is not cheap.
