I'm a little curious about the "my bag soaked through" comments. Does it really matter if you have a down vs a synthetic bag if it is "soaked through?" You are going to be wet and miserable regardless and I don't care what they tell you about "synthetic keeping you warm even if wet." Yeah, synthetic may dry a little faster but if it is that wet out, nothing is going to dry. Use a super cheap bivy sack, and any bag you buy should stay dry unless you jump into it while absolutely sopping wet (not recommended). Bottom line is: Buy the bag you want, use some common sense, and go huntin'.
Depends a lot on the shelter too!
I just bought a used center Zip Kifaru, hand washed it in the bathtub, rolled it tight squeeze the water out, it felt almost the same weight after rolling it it did prior washing and was completely lofted again, the Apex insulation in it has 99% heat retention soaking wet as compared to dry, don't think you will get that with soaked down. To me that is the difference!
Is this your standard procedure at 11,000 ft in a rainstorm that's been lasting for 3 days and you, your tent, and your bag are soaked? All this "synthetic insulation" advantage talk is laboratory theory. I also have a 0 deg center zip slick bag and have used it a lot. It is probably one of the better syn bags on the market but it doesn't even come close to my down bags for weight, bulk, and more importantly warmth. I've used a down bag for years and neither condensation nor rain have ever made the bags unusable. If I was hunting in BC I might reevaluate but it's CO. Take some precautions and use the bag you want. Down Technologies are so good now that the water argument is pretty much moot. Western Mountaineering has thrown their down bags in a lake and they are still dry and floating after days of being there. They don't even have treated down. Call and ask them about it. GOOD down bags are underestimated for their stowmworthiness.
