Drawback to this kind of test is that you will likely see 100% passing rate with any decent gear. Keeping rain out is rarely a problem in my experience. It's water being forced through by walking through brush, crawling, sitting, rubbing on packs, etc that "fails" W/B rain gear.

I agree completely. I think a simulated rain or shower test is a good start, but any rain gear worth a damn, will pass that easily. I think this will have to be more of a comparison review. It is going to end up with the findings being based on personal preference, but with the real world conditions, and a variety of gear to compare, I think we will get a lot of useful information. Thank you, High Country, for taking your time to do this.
