I can only speak to this product from the perspective of someone who wanted a great fitting go-to winter
jacket that could be worn on top of several layers (a thermal crew, a sweater and perhaps a fleece). The
jacket by itself fits me like a glove, however there was little to no room for a fleece to wear underneath of it. The Solar Wind
Jacket is very thin, lightweight, and compact. It is by no means a full-blown winter
jacket. Also, I'm 6' and the
jacket stopped just on my belt-line and a bit too short for my liking. I could go a size up to resolve all of these issues, however I'd lose the amazingly tailored-fit that
Patagonia is known for. I returned the
jacket because it really didn't serve a functional role in my wardrobe, but if it sounds like your kind of
jacket by all means try it out, as it's probably one of the best of its kind.
