Combined bag temperature rating
I'd like to get some opinions on this.
When you combine two bags (one inside the other) how much does the combined temperature rating go down?
For instance is a 30 dereee bag inside a 30 degree bag equivalent to a 0 degree?
Specifically, I have the GG lightweight bag that was discussed on this list a month or so back (50 degree rating, I think) .I also have an Eddie Bauer Bag liner (a poly blanket with zipper). Then there is the poncho liner I just bought (I slept comfortably with just it last night.-- low of around 60 degrees)
What temp could I be comfy at with combos of those three items??
I'm still playing with gear to optimize overall bulk for a given temperature.
When I win the lottery, I'll buy down and be done with it, but until then--- the dance goes on.
