choosing a sleeping bag?

[CNCTEMA]

This may come as a surprise, but I use my " North Face" sleeping bag to dry my hunting pants as I sleep. I hunt in cabelas camo bear cloth pants..that's just real fussy fleece.My North Face is an older model rated down to -40. I don't think it would actually insulate to that temp though. Temp. during hunting season here in Alaska is usually 28-60 F. Ive been doing this for about 10 years so I don't think it's just luck, I think that there's just enough insulation to pull off a great drying act..I've used this all over the Brooks range both north and south range.

Its not so much the quanitity of insulation as It is the kind. Don't try this one with down too often, folks.
