SprinklesOriginal150 0.3The REI brand ones are nice (and true to the temps they say they are good for). I have an REI three season single, and have used it to just below freezing with no problems.
oldplancktimer 0.3When not backpacking I use a rectangular bag like the Rei hunker down. For really cold (<20) I just use two, one inside the other, along with layers and a warm hat. The rectangular shape is fine for some movement and side sleeping and it’s the same dimensions as my sleeping mat and cot. I wouldn’t want to go much bigger or the space inside is too large to effectively warm with body heat.
Autoimmunity 0.1Eh, depends on your use case. I'm in Alaska and I use a 20 degree rated REI bag. But I'm also not camping in colder seasons. If I were going out anytime other than between May-October, I'd have a -10 rated down bag.
