1.  I'd have to agree that down is *particularly* useless when wet,
probably more so than most modern synthetic fill materials.

2.  That said, I've never (knock wood) had to deal with a wet down
bag while hiking.  A kitchen garbage bag is all it takes to keep the
bag dry, even in the most extreme conditions.

3.  To broaden the discussion just a wee bit... the bag (whether it
be down or synthetic) isn't the whole story.  A reliable tent is also
key to staying dry and warm.  It serves several purposes: to keep
you dry, to block the wind, and to provide yet another layer of
insulation between you and the elements.
