used this bag for five nights in 5 degree or so night time temps and I was toasty warm, very comfortable and for it's rating packs down well and is nice and light. I like the double zip design which let's you stay warm while doing things in your tent. The condensation from my tent would get the shell pretty damp but ten fifteen minutes in the sun and good to go. Definitely recommend this bag
