I just picked up a Showers Pass touring jacket. I haven't had it out in the rain yet, but I can give you mu initial impression. I'm 6',1" with a 36" sleeve and a 46" chest. I usually wear at least a large size jacket, but I tried on a large at the store and got lost in it., I bought a medium and still have lots of room for layers underneath.

It's a heavier weight jacket than I anticipated, and I'm a little concerned that it might be overkill for commuting in North Texas, but I also got it for touring in the Rockies and some Northern states, so it should be the berries for that.
