Went out this weekend to some nearby woods - the weather was stunning and we found a great spot (albeit with some whoopie sling issues ive mentioned in another thread), anyway, for some reason (i'm blaming the hip flask for this one) i decided that my lightweight down sleeping bag would be enough to keep me warm, with nothing between my butt and the woods other than my hammock.
Sure enough, at some point during the night, when the temp got down to about 11-12 degrees C (thats about 52-53 for you boys across the water) i woke up with cold shoulders, hips and a backside. However, i'd also been sweating enough to soak my sleeping bag thoroughly. I hadnt had that much to drink, so i wasnt too worried about it being anything else, but i did notice some condensation on the inside of the hammock in the morning.
I'm using a DD Travel, and i know that they're not that breathable, but is it really possible that my sleeping bag kept me that hot on top, but the air outside got me cold enough to wake up - surely my body would circulate the warmth and create an average temp. Is it possible it was condensation and not sweat? I didnt have the netting zipped up, but there wasnt much of a breeze. Or perhaps my body didnt like the evening tipple and knackered its ability to regulate temp?
