Cannot help you out here too much but good for you that you are thinking ahead to winter. I do the same. Better to be prepared for the next season.
Is the jacket waterproof? Since you commute is short, that might be a good idea. I think areotech has a nice waterproof jacket but it gets REALLY warm even when it is raining and cold out.
Last year, I just sucked it up for the 22 mile RT trip. I still need to dial some stuff in but it worked last year.
Do you have a link to their jackets?
