I need some guidance/advice.
This season I have slept out 4 nights so far using two different Big Agnes down bags/pad combinations rated for 15 and 20 degrees. Temperatures have ranged from 35F to 47 F with calm to moderate winds, on each separate occassion using hammock, tarp, and large car camping tent. I slept with one bottom layer and one or two top layers along with cap or hoodie. I was not able to sleep comfortably through part of the night due to feeling cold (but no shiver). The only night I was able to stay comfortable the whole night was when the low temp was only in upper 50s. Why am I sleeping cold with 20 degree rated bag?
