Let's start by saying I agree with Christopher's ideas.
> How are you able to keep your feet warm in 30' weather while for instance hanging out in camp?
Oh, that's easy.
Find camp site.
Throw my wife inside to sort out the interior.
Go and fill water bottles.
Get into tent, onto air mat (this is winter, right?) and remove shoes and day socks.
Dry feet. OK, if they aren't soaking, sometimes they get to air dry.
Change to thermals etc etc for warmth.
Then, if cold, put on tent socks. These are very fluffy socks I bought years ago near Chamonix and which have NEVER been inside a pair of shoes. Zero compression. Don't have any down booties - sigh.
Start cooking dinner.
Go to the loo outside (change to old socks and shoes for this).
By now it is dark, so go to sleep until Sue wakes me up and demands breakfast.
Hidden behind all this is the idea that we don't stop so early that we have to 'hang around'. OK, if it is really early, we might go free skiing or climb a peak or something. Even go for a wander with the camera. But NOT 'hang around camp'.
That's what WE do. Doesn't mean anyone else has to do the same.
