Michael, I bought two Westcomb Shifts recently, a medium and a large. I've now worn mine (the medium) on four weekend trips, and saw sustained rain on two of those and intermittent rain on another. The Shift feels much more breathable than any other jacket I've owned, including my Rab Drillium eVent jacket. I had no leakage at all after hours of continuous rain in Olympic National Forest. Also, the Shift has a quiet, matte, somewhat stretchy, softshell-like face fabric, which I like much better than the more conventional plasticky hardshell fabrics.
I don't have a use for the large Shift I bought. It is black in color, unworn, with tags, and I'd be willing to let go of it for $200 if you're interested in it.
