I wear a down vest almost daily in the winter, since it doesn't get terribly cold in GA. Don't laugh but I got mine at the GAP about 3-4 years ago, and it is still going strong. I like them because I can still have a free range of movement but still be very warm. I'm 50/50 when it comes to the filler. Goose down is very warm, but bulky, and doesn't dry as fast if it gets wet. The Thinsulate filled ones don't seem as warm to me, but they are more compact.
