Just submitted an answer to a question on Patagonia.com about the Down Sweater and the Nano Puff.  Curious to know what others out there think.  I like the classic down look and feel but the new-tech properties of synthetic fill are a nice advancement.  I have a few months before my next rainy European excursion so we'll see.
