Honestly curious, no flames. How many consecutive nights have you backpacked or bivvied on Kodiak in Fall without any heated shelter and without any hard roof, using a down bag? Am wondering how long a down bag will retain loft in high humidity and relentlessly wet conditions. Backpack nights in elk country does not count laugh unless it is Roosevelts on the West End of the Olympic Penninsula!

Good tip on getting the warm air out before moisture condenses. That will reduce the amount of condensation. Have done that but am also reluctant to stuff a bag with any trace of dampness in it, though we have to sometimes, then dry it at home.
