I reckon it must have been about 5 or 6 degrees last night. I was under cover but it was a bit draughty, I slept in a quality down bag with a (female) comfort rating of 0. I was on top of an Exped Synmat UL and I wore a base layer, 100wt fleece top and a RAB Generator smock ... and I wasn't warm
'Sleeping cold' seems to be getting worse the older I get. I'd had my tea before I went out, had a brew once I was pitched up, wasn't wet and hadn't flogged myself to death geting there. I'm begining to think that it's just one of those things ... anyone else suffer?
On the back of a chest infection I slept cold last night. Phd minim 300 in a tent in my montane puffa jacket and hat. And I'm getting older too. 4 am pee saw me chill down.
I lost 40kg five years ago and definitely felt the cold. Went from being toasty under a Jacks R Better under quilt to needing a minimum of a three season bag. Fat is definitely warmer. :D

I've really noticed the difference in temperature with the low (no) carbs diet nonsense but then again I've also lost a stone in weight and so maybe that's just the fat too - hard to know really int' it???
I read several times that people who live in cold climates believe a high fat diet will keep you warm but to avoid sugars as they are quickly 'burnt' calories and end up making you feel colder - whale blubba for dinner should sort you out! (ps dwindling thyroid function also makes you intolerant to the cold - more common in women though!)
