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).

Poor analogy - actually, igloos and quinzees can be nice and warm (well,
compared to a tent or open air).

Your other points are valid - using a vapour barrier at higher temperatures
than ideal may increase your warmth, but decrease your comfort. I wouldn't
use a VB until the temp is cold enough to warrant worrying about wet
insulation from insensible perspiration.

Mike,

You snipped off the rest of the sentence, which said, essentially, that
igloos, while effective, are difficult to fold into the kayak. I guess
Ididn't make that part clear.

From what I've read, igloos can be very effective, though I've no experience
with same. I have dug snow tunnels, however, and they are downright balmy if
you are dressed appropriately.

Or I read too fast - sorry. I prefer to use the snow that's there, no
need to carry any around :-)

What I love about them is sleeping in absolute darkness with absolute silence.
I have not experienced that in any other environment.
