I will admit I haven't spent much time looking into the latest (Sitka, Kuiu, Simms, Huk) breathable type rain wear in the last 5 years. My experience with all the gortex stuff is it works well in a light rain and for maybe 2 seasons. After that seam start to leak and any hard rain will get you wet. The pressure points were always an issue with the membranes as well, sit down on a wet boat seat or sit down on wet ground and you will get wet.
Is this still the case with this latest stuff? How many seasons do you expect to perform as it did when new?
Currently I wear the Helly Hansen Impertech II stuff and the same jacket and pants has met my needs for the past 10 years. A couple SE Alaska bear hunts, fishing, waterfowl hunting, and just general use in the rain. No membranes... but light, durable, and doesn't let water through.
