Confused about sleeping bag temperature ratings (lemmy.world)

Where I live it rarely gets down to 32 degrees. I bought a bag that said 20 degrees. After reading the manual it said that was the extreme rating. Will this bag keep me warm at 32 degrees or not?

Get a sleeping bag liner. A flannel one will cost about $30 and boost the warmth of your sleeping bag considerably IF you need it.

Pro tip: If you are cold in your bag when you shouldn’t be it probably means you got too hot, started sweating, and now your cold because of evaporation. It took me YEARS to figure that out. I now leave my bag unzipped half way down so I don’t build up moisture inside and that keeps me from getting cold. I’ve comfortably slept in my bag many time in air temperature well below freezing since figuring that out.

Yes, I'm looking into sleeping bag liners to see what I like. But, I didn't know about the unzipping of the zipper. Thank you for the tip.
