Used the -15 version on a recent trip to the smokies and ended up having to put on my down pants and down coat to stay warm when the temperature got below 10 degrees. I know most bags the rating is survival and comfort is usually 15 degrees warmer but still thought it would have done better.

Great lightweight bag 0°
Well made bag, excellent loft and good insulation placement through the bag. I am 5’ 9” and the regular length bag is about perfect in length. I would recommend the longer bag for anyone taller than 5’ 10”.
The compression sack as a nice roll top dry bag, and is a nice addition. Looking forward to putting this bag through some Alaskan hunting trips this fall.
