Nylafume pack liner if you're that concerned, or a trash bag. Dry bags are a thousand times overpriced for what they doI'm too chicken-s**t to do this.
My nightmare is having my down sleeping bag/quilt somehow get wet, and then a snowstorm rolls in...
I know for sure I'm falling victim to the "We pack for our fears" thing, but I just can't shake the paranoia. A dry sleeping bag can save your life in the mountains. So I run a drybag.
Definitely adds weight, and not as efficient (voids in pack.)
