No, but this guy did. It sounds interesting.
I was using my Kifaru Zero degree Slick sleeping bag. This is just an amazing thing. I don't understand all the physics, but I can get into that bag literally soaking wet completely dressed. Soon the interior of the bag is almost unbearable, like being inside a wet trashbag. Then, fall asleep and when you wake up, friend you and your clothes are DRY, no kidding. Not so lucky with the guides down coat or bag.....I think that's where all my evaporative loss was going.....he was miserable, chasing moisture the whole trip. Leaking boots, soggy coat and sleeping bag, and weather uncooperative for drying. I'm glad I went with the Synthetics.
