Vapor Barrier for bags - 08/29/08 12:07 PM

I've spent quite a few years sleeping in bags with down and noticed that in humid conditions I always felt colder. Well, after much looking into over the years it became apparent the 'humidty' was coming from my own body as much as the environment.

Along came 'Dry Cleaner Plastic bags' for my own cheap 'Vapor Barrier bag' when i could'nt afford the commercial ones. The Dry Cleaner Bags weigh next to nothing, pack small, are quite durable with some care, and work essentially like the expensive ones. I lay the dc bag inside my sleeping bag with the zip open, climb into it, adjusting as necessary, before zipping up the bag. Some bags come up to my armpits, others are longer and come above my shoulders, both will work. <img src="/forums/images/graemlins/smirk.gif" alt="" />

So where does the condensation from your body go when your sleeping in a plastic bag? I've noticed that when I'm sleeping in colder weather that there is more moisture inside my bag. Cold and clammy.

wear long underwear in the plastic bag that you do not need to wear the next day. after your body gets used to the humidity it will slow the evaporation rate from your skin. vapor barrier is tricky read well on it befire using. wring out long undies next morning after rinsing out and hang on your pack to dry in the day.
