Thanks for the good suggestions. I live in a warm place, and sometimes travel to cold places, or make trips to multiple places. For example, we have family in Portugal, colleagues in Switzerland, so I might make a trip to Europe in winter where I am going from south to north and don't want to carry a million different coats. Or I may travel to san francisco or boston in winter, but not sure how cold it will be while I am there so like to have layering options. I do have a patagonia down sweater that I layer under my arctyrex parker, but not sure I like the puffiness which is why I was attracted to the idea of the pez long sweater. I do look good in long sweaters and long jackets, and like them for the added warmth over the more typical short jackets.
