Congratulations, you made the right step out from the miserable
clueness this thread was stuck into.

The answer is VAPOR BARRIER. This is an air-proof bag you use inside
the sleeping bag to keep it dry from perspiration. In extreme
coldness the sleeping bag frozes within minutes and any moisture just
cannot get out.

What works (comfortably) in winter conditions in, say, Finland, Minnesota,
and the like. is a lot different than, say, what will work on the west coast
of the US. Even in Washington, you have to worry about external, not
internal, moisture. I'd drown in my own sweat in such a rig. I doubt not
your knowledge of winter kayaking in cold weather and would probably emulate
your choices (though I'd probably go with a dry suit, it just makes paddling
more comfortable). It just doesn't get that cold on the coast here (40F-55F,
rain, wind, and fog). Santa Barbara and south is a different story. There,
you will have warmer water, weather, and less rain.

That said, a wet bag is worse than useless. The first priority is to keep it
dry from the elements. The second is to keep it dry from personal
excretions. For those in rainy conditions, a polartec bag is probably the
way to go. For those who are worried only about immersion in water, any bag
will do that is properly protected from bilge water.

As you point out, any bag that is wet and then freezes may function as well
as an igloo, if it's thermal integrity is not seriously compromised, but
it'd be difficult to repack in the boat (grin).
