I think most of us have experienced dew, condensation, inside-of-tent-water-spills and the like and gotten our down sleeping bags damp. It makes for some cold nights. I have never gotten a down sleeping bag totally saturated, but I assume it would flatten out and not provide any warmth at all. I'm too careful and I never want to deal with possible mildew build-up.
Now what I wonder about is sleeping in wet synthetic sleeping bags. I've gotten synthetic bags damp and didn't notice anything, but never soaked them all the way. People always say that synthetic sleeping bags will provide warmth when wet. Common sense says that it's probably going to be miserable to try to sleep in a moist sponge, although if you wring it out it might not be so bad–or would it? I don't know.
Can anyone debunk this myth or give credence to it with a pleasant experience sleeping in a wet synthetic sleeping bag some night?
