I thought this was easy until I started. Clothing for a week-end or a week is a doddle, change of sox and underpants and away I go. 3 weeks is different as the length of time away will make at least on rinse of the next to skin layer mandatory.
Also a complete change apart from the emergency dry layer may well be worth while packing as well as sleeping gear to keep the bag clean and dry.
For in camp use I may add in a pair of Polartec pants [ modified with extra knee padding ] and a fleece jumper or jacket but as we may be cutting firewood I was wondering whether or not to put in my old army field pants and parka also I still haven't decided between my down parka or my poly insulated belay parka.
I really think I need one extra set of clothes, especially if the stay extends to 4 weeks or more.
Input would be appreciated
As I am dragging the sled I'm guessing I can add 5 or 6 kilograms of extras
