I just picked up a Western Mountainering Apache down bag. It is rated at +15 and weighs 2lbs. It has all the goodies like draft collar and draft block at ziper. I will test it in the next week. The material is very water resistant so I am not sure how well it will wick water away. I plan to climb in it damp and see how well I sleep outside at whatever the temp is next weekend. Unless it is very cold then I might give it a little while. I will keep you all posted.
The guy I baught this bag from insisted I will wake up dry and the moisture will be on the outside of the bag. I am skeptical but he said I could return it if it does not perform.
