As opposed to just being heavier than you could get away with, can a fully zippered bag or quilt be too warm?
My vote is no. If you get too warm, you unbuckle/unzip, stick your arms and or feet out, or just lie on top of the thing if it's really hot. Since this is what I do at home (I use the same thick down duvet all year round), it seems perfectly natural and sensible to me. But I see many posts with folks asking if a certain sleep system will be *too warm*. If you are in the *too warm* crowd, then what is it that is too warm? Do you wake up and find you can't get back to sleep if you adjust you bedding? Are you used to sleeping in a temperature controlled environment at home? Or are there other factors that make you feel that some bags/quilts are too warm?
