Cheers Mole. I do have a platypus and sleeping with it might be the way to go. I cook with gas & I'll stick the cannister at the bottom of the bag too (I hadn't thought about this).
I hadn't considered my face: that might be an issue but as no-one is around I guess I can don my boxer shorts on my face if it does get uncomfortable.
My bag has a comfort rating of -5 so with my thermal long johns on & fleece liner I reckon I should be ok but that is partly why I wanted the thermometer to gauge it more accurately.
I can always put some layers on anyway but I prefer not to if I can get get away with it.
Where are you going in Wales Mole? I know you are a regular Dartmoor man.
