As folks have said lots of good choices. I think most folks can get a lifetime out of a well cared for down bag ( especially if you end up with couple for different applications). You can read about fills and fabrics, but for me sizing is the wild card. Getting something large enough for me and what else is going into the bag is pretty critical.

My first down bag, I got too interested in getting a bag with maximum loft and minimum weight and it ended up as a bag that was not comfortable for 14hr winter nights. If you can find a WM dealer with some stock who will let you lie down in a bag, I think its worth it before you drop the coin.

The collection of taxes which are not absolutely required, which do not beyond reasonable doubt contribute to public welfare, is only a species of legalized larceny. Under this Republic the rewards of industry belong to those who earn them. Coolidge
