I have talked with many climbers about bags and received all sorts of
different opinions on down vs. synthetic. They agree that down is
lighter, more compressible, lasts longer, but loses insulation power
if wet, and is more expensive. According to many of these climbers
certain factors make a down preferable and others a synthetic. If
there is a good chance of getting the bag wet even from your own
perspiration and you really need severe cold protection, use a
synthetic. If you are conerned about the life of a synthetic bag, buy
one with a lifetime guarantee. When it loses loft send it back. If
weight or compressibility is more important than getting all the
warmth out of a moist bag, buy a down one. Some of these climbers
also said that since down bags compress easily, the R value on the
bottom of the down bag gets quite low when compressed by body weight
making it necessary for a good rest pad. I don't have any data to
back this up but it makes sense.

I personally use only synthetics because I often get too warm while
sleeping and sweat excessively. I wake up soaking. This would scare
me if I were in a down bag and were in a severe cold environment. I
really like my The North Face Tangerine Dream (-30 degree) in this
respect. It has a Coolmax liner which sucks moisture away from me. I
don't feel soaking just steamy. The moisture just goes right through
the bag and freezes on the outside. I just bang off the ice in the
morning.

If I try staying a bit cool while sleeping, I don't sleep well. If I
get a little cold, I can forget sleeping altogether. My climbing
partner, Alex, thinks I have a body temperature regulation problem.
He is just the opposite. He sleeps well cold. He took a Kelty 25
degree bag (that is more like 40 degree because of loss of loft) to
Ranier and slept in 4 degree weather. I would have died. He has sent
that 25 degree bag back 3 times and they just send him another one.
He says he will do it again soon. He has a Feathered Friend Eider
(-30 degree) which he normally uses for anything below freezing. It
is very light at 3.7 lbs. My TNF Tangerine Dream is 5.4 lbs.
However, unless it's very cold, I don't take a rest pad, because my
TNF bag provides plenty of bottom R value and cushioning. He takes a
1.1 lbs pad so his total weight is 4.8 lbs. Then the difference is
only 0.6 lbs. I have the most fun though jumping up and down on my
Lowe compression stuff sack trying to get my bag small enough to fit
properly in my 7000 CI backpack. Alex just easily stuffs his Eider
into its sack. Before I got the Lowe compression stuff sack, I used a
The North Face sack, but I had to have Alex carry my bag in his 10000
CI backpack and I carried his bag.
