I forgot what my bag is, and it's buried right now...
BUT I'm chiming in just to share that a lousy sleeping bag really inconvenienced me on my 14-day Alaska float hunt in 2013. It was TERRIBLE to get bad sleep each night, in a bag that was too small and too cold. I just read my trip journal again the other day, where I railed on that bag every day. I had a bag that worked well on 1-2 day trips in the lower 48, after I'd moved out of Alaska and started camping in warmer climes. But this was years later, and a few pounds heavier, and I also had to sleep with some diabetic supplies in the bag with me, to keep them from freezing. The bag said it was rated to -25... that was a joke! Man, was I miserable.
The first thing I did after landing in that bush plane back in Fairbanks was to go to Beaver Sports and buy a really good bag... but the trip was already over.
