Grand trunk sleeping bag?

[TimberbeastWaco]

I went to bed in the 80's slept on top of it till 0400 when I woke up in the low 70's, (I also used it down to 68F) and got into it, I liked it, It did as advertised kept me warm although sleeping on a angle is hard to do I still slept very nice.
Hope this helps.

Update, I have been using mine for a few years now as a top quilt, I unzip one zipper making a foot box, along with a thick poncho liner down to 40 F.
