If under a rain fly/tarp/tent, is heavy mist a problem with down?
Why I ask/my recent experience:
Rain not predicted on my last trip so I just slept under some bug netting. Being right on the coast however, a really heavy mist rolled in at night. So heavy it sounded like it was raining because it would build up on the trees then fall as droplets.
Anything not covered the next morning was wet, including me and my down bag. Only the top layer of down wetted out, so it didn't fully collapse on me, but it was concerning!
So if I would have had a tarp over me, would I have been fine? Or would my down have been screwed either way?
A big reason I am worried, is that this happened with a fairly heavy 10° bag, and I am considering moving to a zpacks 20° bag, so I will have less down, and lighter material, and will get a complete failure sooner.
