Shag:
I am not using this bag for backpacking, but in a base camp. I am not a big guy, avg. size. I will not be seeing temps -20 to 0F, but more likely no colder than 15F. I do have a Black Diamond Bivy sack that weighs less than one lb. and does warm up the bag a bit. I don't know whether the Big Agnes bag, which I have not purchased yet, will even fit in the Bivy sack.
In colder temps, I pack a closed cell pad below a $10 Walmart 8" thick air matttress that I blow up with a pump.
When final decision is made I will LUK what I went with, why and how it is working out the same as I did with my tent thread for this same Wildland Fire Medical Suport job.
