Appreciate the recommendations, all. I should clarify that I've been winter commuting for several years and I'm fine with layering, I just need a new shell. I prefer a mere shell, so I can use it in warmer temps as well as colder temps (varying the layering underneath). I basically want another showerspass jacket, but one I don't have to constantly glue and sew back together, from a company who actually returns emails if something goes wrong.
I'll look at some of the Gore jackets. I've also been stalking the winter riding forum on bikeforums for additional recommendations.
