I have one to add:  Bring wool.  If you've ever needed it and used it when it's wet and still kept warm you will appreciate the comment.  I pack 2 layers of wool whether I'm canoeing, hiking, hunting...it's an old bit of knowledge, but important.

 Wool is a classic, but for some people, me included, I can't wear it for comfort reasons. I itch like crazy wherever it hits my skin.
 For people like me, Fleece clothes are the way too go.
Light/warm, doesn't hold body odor, you can "spin dry", (like whirling a wet towel), lighter than wool and can't hold water.
Drawbacks? Unlike wool, fleece melts when near a fire, but unless your a moron, you shouldn't be setting yourself on fire ;D
 Bottom line, EITHER are way better than cotton or WET Goose Down.
