For the past two winters, I've worn an Arcteryx Atom LT jacket. It is not windproof or waterproof, but it keeps me warm and dry. I don't think I'll be wearing a rain jacket again because this jacket is so fantastic. Like wool, it stays warm when wet. It's hard to describe. It absorbs water but it doesn't get uncomfortable. As I type this, I wonder how anyone can believe me, but it's true.
