as far as fleeces go..... If you want real warmth, down is your only option), but this is a 'wear it around town" solution. Down is not actually fun to wear,; its functional. This is like wearing the most plush blanket everywhere with you. I own the warm 3 and it is 1/5th as soft as this one (Go with this one :) ).
It's pretty darn wind resistant (for a fleece), but I would not wear it on a cold windy day without a shell. This piece gets worn more than anything else I have.
