In a question a bit related to Winter apparel for Europe (November-December), would a leather jacket (thinner lamb jacket) be okay for traveling Spain/France/Italy during November/December?
I also plan to take a SmartWool longsleeve base layer + (t)shirt + hoodie. Would that be enough layers? I also have a not too thick down puffy jacket but I guess it is way brighter (brightish green).. and for some reason I wanna look "good" in Europe :). It would probably be warmer though.
I'm currently living in San Diego, to give an idea of what I'm used to now, though I did lived in Seattle for a bit, and the puffy/down one kept me warm enough by itself during winter, the leather one was a bit chilly if worn by itself, but I never tried with a proper base layer and warm middle.
I'm planning mostly to visit cities and towns, not snowboarding or so. For France (which I believe is the coldest of those 3 countries) pretty much just Paris and nearby towns. Italy is where I'll spend most of my time, and my plan is to start in the north and move south all the way down to Sicily, where I would be ending my trip and coming back home.
As an aside, are rain jackets really needed/recommended? Or would a simple expandable umbrella be enough?
