Okay folks....I know this question has probably been asked a million times but I need to ask it anyway.
Down or synthetic fill for a mountaineering bag? I understand that a down bag is highly compressable, warm, and must be kept dry, and weigh less that synthetics. I also understand that a synthetic will insulate when wet but is bulkier and heavier than down.
So....with that said....for those of you that use down for mountaineering / climbing....how do you go about keeping it dry? You use a bivy sack? If so....what are the best bivy sacks out there? I've been looking at some of the sacks made by Integral Designs with the eVENT fabric. eVENT appears to be better at breathing than Gore-Tex according to the gear reviews I've been reading.
F*ck....looks like I went on too much. SO...down or sythetic. That is the question. What do you prefer and why?
