My thoughts exactly, but when I go to an outdoor shop this time of the year (or look at fe Fjällräven's catalogue of this season) most jackets are quite insulated despite everyone always talking about the layer principle... Really annoys me because I'm not interested in one of those for active outdoor activities, and I wouldn't recommend them for most situations either...
The old Greenland jacket works quite ok as a shell. There is also the Fält jacket, and a few cousins. All will more or less do what you want.
