plenty of layers, decent doss bag and from past experience I find being stretched out on a sleeping mat / bivi bag next to the fire to be much warmer that sitting in a chair next to the fire. I would avoid the booze altogether when its this cold (b*gger getting up at 0400hrs for a pee when it's that cold). But the main thing to enjoying it is to have an easy accessible "extra warmth option" - this for me is generally my ex-issue bulky artic bag sitting in the bag of stooboys motor that i know i can lay my hands on quickly (if we are near enough to the motor) this makes a big difference with me enjoying the night knowing I can get a another very warm bag
Ermm another slightly wussier addition is a hot water bottle for when you first get into your bivi - just make sure to chuck it out of the bivi when it gets "nearly" cold.
There is simply not enough opportunities to get out during a year to discount the colder months imho. (plus no flying things to eat / sting you)
I am sure it will be a great outing - jealous now cos I am booked up for the next couple of weekends - enjoy mate!
