Brave little toaster
I have camped in almost every condition with this bag and absolutely love it. The only complaint I have is that it can get too warm! A quick unzip though and life is good again. This bag is coated with Marmot's version of Gore-tex (MemBrain) and it keeps all external moisture out of the bag. I can easily pack it down into a size L Sea to Summit eVent compression dry sack. If you are wanting a bombproof bag that wont let you get cold, consider this one. It does have a steeper price tag but is worth every penny.
