Will it all go in?

I look at the trekking kit and clothing for over a month all laid out and wonder how it's all going to fit in the two bags. We can only carry as much luggage as the internal Tanzanian flights operator will allow, so the generous KLM allowance means nothing, as Precision Air's 20kg/1 bag each limit will apply.  Out of respect for our porters we are trying to do minimalist on the trekking clothing. There's no shower/bath for a week so there isn't much point in a full change of clothing every day, as one will stink anyway! However, there must be sufficient layers so that, when all put on together, they will keep us warm on summit night.

There is always the possibility of our luggage going astray during travel. Therefore, we will be wearing/carrying as much of the essential stuff during the flights. We can hire most equipment there if we need to but we wont be letting our expensive walking boots or outer coats out of our sight, so we will be looking very silly and wearing them - only a fool would trek a mountain in a pair of rented boots! If the weather forecast here for Wednesday is correct (heavy snow), we will be dressed appopriately to get to the aiport.
