Took this backpacking for three nights and it packed down smaller than my old bag ever did. The mummy shape keeps heat in without feeling suffocating, and I actually appreciate that it's made with sustainability in mind. Couch surfed with it once too and it worked just fine.

Slept in this on a 35-degree night and stayed toasty without feeling clammy. The lightweight build meant it barely added any weight to my pack on a three-day trip. Only gripe is the stuff sack is a bit tight, but that's minor.

The mummy shape really keeps the heat in, and I stayed warm even when the temp dropped close to freezing. It stuffs down small enough to strap to the outside of my pack without adding much weight.
