I would look for a 0-20 degree down bag. Down is more packable and far more comfortable and thermo regulating imo than synthetic. I have a 20 degree big Agnes down bag and have camped in 20 degree weather without a problem. Just slept with longjohns under my pants and a wool baselayer on. Very cozy.
r/backpacking • One versus two sleeping bags for winter backpacking? ->Have a Big Agnes 20 and a Magma 20. Both down both compress well. A few years ago, I switched to those liners in the summer and love them. Warm enough in July. Pack extremely small.
r/REI • Best sleeping bag that packs small? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
