I've spent some miserable nights in a soaked down bag....but not in the treated "Superdown" KUIU 15*F bag I've had 5 years. Last year on a moose hunt we had a leaky (unknown to us) water jug in the tent. I was sleeping on the ground on a thin pad and woke up in puddle. I figured the down bag would be wet for a long time...but it was dry in few hrs of hanging up. Works very well and stuffs into a very small package. And their Superdown puffy jacket and pants are good too. I'm a believer in treated down...my Mt Hardware synthetic bag is reserved as a loaner for my nephew when he comes up to hunt with me,
