View Full Version : Combined sleeping bag temp. rating

10-02-2009, 16:12
I just spent the last 45 minutes using the search function and I didn't find what I'm looking for. Maybe one of you can help. Some time ago there was a thread here at Whiteblaze about using one sleeping bag inside another to get a temperature rating lower than either of the two bags seperately. There was even a mathimatical formula for figuring the final temperature rating if you knew the rating of each of the seperate bags.
Can anyone point me toward that thread (maybe you saved a link to it) or repost the equation to figure the final rating, if yo uknow it.
Thanks in advance for the help!

It was inside another thread that may be worth reading too.
